Infrared thermography: A powerful tool in mechanics of materials
Prof. Jean benoit Le Cam
The design of industrial components requires to take into account thermal effects during the deformation of materials. For example, an increase of one degree in tire during driving will induce a significant decrease of its lifetime. Therefore, it is necessary to characterize phenomena that produce heat during deformation of materials and structures to better design them. This is the reason why infrared thermography appears as an interesting technique of characterization. Moreover, this technique enables us to investigate the calorimetric response of materials, which is of paramount importance for modelling their behavior. One of the main difficulties lies in the strong multi-disciplinarity between thermal, optics and mechanics, with numerous challenges that will be highlighted during the talk from illustrative examples dealing with elastomer and glass materials.
After several years as a research engineer in the Total group Prof Jean-Benoît Le Cam received his PhD from Ecole Centrale de Nantes in 2005 and has since worked on fatigue damage and fracture mechanisms in elastomers. In 2006, he joined the academic staff of the French Institute of Advanced Mechanics (IFMA) as an Assistant Professor, where he developed the mechanics of elastomers. In 2010, he was appointed director of the Structures and Mechanics of Materials departement at IFMA. In this period, he has extended his research field to quantitative calorimetry in mechanics of elastomers. In 2011, he joined the Institute of Physics at Rennes University as a Professor in order to create a Quantitative Imaging Group and to study mechanics of elastomers and glasses. His industrial partners belong to various sectors of engineering: automotive (Michelin), oil pumping (PCM) and anti-vibration systems (Cooper Standard), to name a few.

If you were due for a heavy dose of ingenuity, the University of Arizona was the place to be yesterday as more than 350 Engineering students displayed and demoed the results of their year-long senior projects.
Solar power ruled, rockets fascinated, cameras detected, medical devices remedied, and sustainability was front and center at the 2014 Engineering Design Day, held May 6 in the UA Student Union Memorial Center and on the UA Mall. Top design teams took more than $14,000 in prizes.
There was the modification of a street sweeper to make it into an efficient onion bulb harvester. For their clean, low-cost design that simply worked well, the multidisciplinary team won the Sargent Aerospace and Defense Voltaire Design Award.
A coveted $1,000 Texas Instruments Analog Design Award went to the team of electrical engineering and systems engineering students who created a meter to detect the power consumption of different devices in homes and businesses.
Students at Tanque Verde High School in Tucson, Arizona, have new educational opportunities and home-grown vegetables and fish, thanks to an agriculture and biosystems engineering team on the greenhouse aquaponics project. They won the Rosemont Copper Best Sustainable Engineering Award.
Two teams created award-winning solar-powered camera systems for a desert environment — one for detecting border crossers, another for monitoring soil erosion.
A $770 automated time-lapse camera system to remotely monitor soil erosion was ready to start collecting data this monsoon season on the Walnut Gulch Experimental Watershed near Tombstone, Arizona. The system will sense rain, take photos at 30-second intervals and deliver them on demand to scientists at the Southwest Watershed Research Center.
“Before, someone had to be there on site to monitor the erosion,” said team member Deanna Johnson, a mechanical engineering major, adding that she felt fortunate to work on a “customer-oriented, industry-related project with a client who did a great job of working with us.”
The team’s work was rewarded with a $750 Best Design Documentation Award from Technical Documentation Consultants of Arizona.
Judges deemed the proof of concept design for a saguaro border surveillance system the most manufacturable of the projects on display, and the team took home a $750 prize, sponsored by AGM Container Controls. The solar-powered network of cameras hidden inside saguaro cactuses was created to stream images to border patrol agents and help them identify illegal border crossers. Seismic sensors in use now detect movement, but they cannot identify what is causing the movement, explained team member Sean Baker, a mechanical engineering student.
“They can’t tell the difference between a cow and a person.” he said. “Agents do not always know what type of situation they are walking into or they use valuable time investigating nonincidents, so this will actually monitor what is out there.”

In the medical arena, award winners included a wireless flow sensor for cerebral spinal fluid, a self-administered tonometer to measure interocular pressure related to glaucoma, a wearable clinical frailty meter to help identify and treat instability and other problems associated with aging, and a cell phone amplifier for people with hearing difficulties.
Second place for best overall design went to a multidisciplinary team — including mechanical, optical science and materials science engineering students — that created an automobile dashboard quality control system. And an aerospace engineering team won the first-place Sensintel Systems Best Overall Design Award for its high-powered rocket altitude-targeting system. The impressive 10-foot black rocket, constructed partially from additive manufacturing, or 3-D printed, components, towered above more than 1,000 people who turned out to see the Design Day creations.
The most exciting part of the project for many of the aerospace engineering team members: the test launch, of course!
“It was a heart-stopping experience,” exclaimed Austin Mills, who also said he was relieved to see the parachute deploy and the rocket return after its 2,000-foot climb. “Sometimes they don’t.”
The UA Engineering Design Day, sponsored by industry and faculty and supported by judges from local and national engineering firms, is the culmination of the Interdisciplinary Engineering Design Program. Many of the projects go on to become real commercial products.

Faculty and students of the Departments of Civil Engineering and Engineering Mechanics (CEEM) and Materials Science and Engineering (MSE) are collaborating on a Department of Energy (DOE) proposal to develop a fundamental characterization of the structure and properties of geopolymers used for strength enhancement of concrete. The proposal is a collaboration between Dr. Lianyang Zhang, Associate Professor in Geomechanics and Geotechnical Engineering with the Department of Civil Engineering and Engineering Mechanics and Dr. Krishna Muralidharan, Assistant Professor in the Department of Materials Science and Engineering with a focus on developing advanced thermal management systems for applications in energy-efficient devices. The DOE proposal, to be submitted this October, is through the National Science Foundation (NSF), and the collaboration also involves Abu Asaduzzaman, a senior postdoc in MSE, and Mohammad Rafat Sadat, a PhD student in CEEM.
In recent years, researchers have specialized in developing construction materials that are environmentally sound, giving specific focus to utilizing industrial waste byproducts to manufacture products with an eye towards sustainable development. Geopolymers are relatively new materials, developed in the 1960s, that are frequently used for fire- and heat-resistant coatings and adhesives.
Geopolymers have outstanding mechanical properties similar to typical "portland" cement, but they emit approximately 80-90% less CO2 during production, which means the consumption of considerably less energy during production than ordinary polymers. Geopolymers can also be developed using manufacturing byproducts that would otherwise remain industrial waste. Dr. Zhang notes that this sustainable use of geopolymers will make a major impact in the mining industry, where mining waste is a large environmental concern.
Dr. Zhang notes that MSE Postdoc Asaduzzaman is working on understanding what happens with geopolymers at the basic molecular level, and that Asaduzzaman will build simulations at an atomic scale and then will reproduce the simulations in real scale. "Most of the research we are doing focuses on experimental uses of geopolymers," Dr. Zhang says. "However, people still don't understand the building blocks of this material. What is the exact molecular structure of a geopolymer? How do you produce a better geopolymer? These questions are why we want to use techniques to study the molecular structure of this new type of material. Geopolymer materials were first discovered in the 1960's, but they were not used frequently for production purposes until the 1970's through the 1980's. The reason for its growth in popularity is this is a new type of material which is more sustainable than ordinary polymer cement."
Dr. Zhang has been studying geopolymers for the past five years. He says that so far, most research has focused on the experimental use of geopolymers. "Now people are trying to think about how to design materials and in order to do that, you must understand the material's molecular structure," he says. "Water plays an important part in how stable and robust the material is and water helps determine that. Does water break the bonds? Additives play an important part in determining the characteristics of a material. What should be the constituents and proportions of additives that enhance and hurt the material?"
Dr. Zhang also points out that this research focus falls within the framework of the Materials Genome Initiative, referring to a recent initiative by the White House to encourage the manufacture of materials at a faster rate and at a fraction of the cost of traditional materials.
Dr. Zhang notes that the collaboration came about because he wanted CEEM PhD student Sadat to do molecule dynamics modeling, but as Sadat did not have this background, Dr. Zhang suggested an Integrated Computational Materials Science and Engineering (ICSME) course. With this consideration, Dr. Zhang then realized that the materials expertise in the MSE Department would greatly contribute to his research, and this led to the collaboration between CEEM and MSE.
Dr. Kelly Simmons-Potter, a UA Professor with joint appointments in Electrical and Computer Engineering, Optical Sciences, and Materials Science and Engineering, has been named a Fellow of The American Ceramic Society.
Recognition of this honor will be given at the ACerS Honors and Awards Banquet at the ACerS 116th Annual Meeting to be held on October 13, 2014 in Pittsburgh, Pennsylvania. Please join us in congratulating Dr. Simmons-Potter on this outstanding achievement!
MSE undergraduate student Anne Ellis received the distinction of Honorable Mention for the 2014 NSF Graduate Research Fellowship Program. Dr. Erica Corral, Associate Professor in the MSE Department states that this distinction puts Anne in the top class of students in the country for engineering, and we should all be very proud to have her represent UA and our department in all her future endeavors.
Anne plans to pursue a PhD in Materials Science and Engineering at the University of Minnesota through a four-year 3M Science and Technology Doctoral Fellowship she just received. Dr. Corral notes that Erica's commitment to research in Dr. Corral's lab is greatly appreciated and will be missed. Please join us in wishing Anne the very best.
Please join the UA Chapter of Engineers Without Borders for its semi-annual Ultimate Fisbee tournament, Frisbee Without Borders! Frisbee Without Borders will be held on Saturday, April 19, 2014 on the east end of the UA Mall. Same-day registration starts at 1:30 pm and game play starts at 2:00 pm.

Last year, out of all 8 teams, EWB-UA had a new champion and managed to raise several hundred dollars in sponsorships and registration.
Since joining UA Engineering’s department of materials science and engineering nearly a quarter-century ago, Supapan Seraphin has been a tireless ambassador for science and engineering education -- especially for women and minorities who imagined such a career to be out of reach.
Seraphin has received the 2014 University of Arizona Distinguished Outreach Faculty Award, given to faculty with “a significant record of conducting outreach policy, practices, and implementation at the University of Arizona; a record of distinguished creative scholarship; and the sustained application of scholarship in non-formal classrooms.” As a principal or co-principal investigator on National Science Foundation grants totaling nearly $10 million, she has guided countless people of all ages and backgrounds toward successful, rewarding careers in science and engineering.
Seraphin joined MSE in 1990 as its first female faculty member and director of the Electron Microscope Facilities for Materials Research, now part of the University Spectroscopy and Imaging Facilities. Her research centers on processing and characterizing materials at the nano-scale, and she holds joint appointments in the College of Optical Sciences and the College of Agriculture and Life Sciences’ department of agricultural and biosystems engineering.
She has spearheaded dozens of innovative and influential science education programs, including one in which hundreds of first-year UA students and pre-college students visit the UA electron microscopy lab, where they can view, process and analyze data from the microscopes and other devices without getting their hands on the delicate and expensive – and easily damaged -- instrumentation in the lab.
“I love when first-year students in [College of Engineering introductory course] Engineering 102 say, ‘I know you! I remember you from my high school field trip!’” Seraphin said. “One of my highest rewards is when students and K-12 teachers tell me I have provided them with a life-changing experience and had a positive impact on their career.”
Many she touches never set foot on the UA campus. In a program funded by the Arizona Board of Regents, students in Arizona have gained access to the UA electron microscopes remotely, interacting with the instrument operator in real time from personal computers.
Seraphin actively promotes science education to K-12 students and teachers around the U.S. -- including on Indian lands -- and abroad, in such countries as Thailand, Kenya, Peru and Brazil. She is also involved in sharing science and engineering with the local community, as part of “Revealing the Invisible Universe -- from Nanoscope to Telescope,” a collaboration between the UA Flandrau Science Center, Arizona State Museum, and National Optical and Astronomical Observatory that involves undergraduates and teachers conducting programs at science centers and museums to explain the value of UA research to the public.
Seraphin’s other honors for her outreach have included the College of Engineering Award for Excellence at the Student Interface; the da Vinci Fellow Award; the University Women in Science and Engineering Diversity Inclusiveness Award; and the Ben’s Bell Award. The last, given to Tucson residents promoting kindness in the community, was inspired by Seraphin’s famous weekly homemade Thai lunches for first-year students in UA residence halls, supported by funding from the Faculty Fellow program.

The Master of Engineering with an option in Innovation, Sustainability and Entrepreneurship (ME-ISE) degree has been approved and the MSE Department is working towards online delivery and expansion of the program to other topical areas.
The Master of Engineering with an option in Innovation, Sustainability and Entrepreneurship (ME-ISE) has been approved and is now an available degree through the UA College of Engineering. The program is geared toward students and industry professionals who are interested in the translation and transfer of technologically-promising research discoveries into sustainable technologies and processes. It offers a combination of business-oriented classes and engineering courses to help engineers bridge the gap between innovative ideas and sustainable economic development strategies.
One of the goals stated in Never Settle, the UA's strategic plan, is to increase the online student population. In response to this, the UA recently awarded selected companies to assist with increasing online course delivery. One of the companies awarded this responsibility is Colloquy, a division of Kaplan, Inc. (which is a subsidiary of The Washington Post) and a leading provider of online education strategy, consulting, and delivery with 75 years of expertise in global education services. The MSE Department has been working with Colloquy to plan the online delivery of the new ME-ISE degree program. Colloquy will also provide recruiting, marketing and retention services. Online delivery of the program is planned for implementation by January 2015.
The MSE Department is also working with other College of Engineering departments to research expanding the program to other topical areas such as Advanced Manufacturing, Transportation, and Water Treatment and Reuse. Delivery of such topic-specific sub-plans would likely go into effect by Fall 2015.
See this link for more details on the ME-ISE program.
UA Engineering students are gearing up for a new semiconductor processing lab course in the cleanest environment on campus.
A new lab class in the “cleanest” environment on campus is helping prepare UA engineering and science students for high-tech jobs.
Cleanroom facilities at technology manufacturing companies are critical for designing and producing integrated circuits, memory devices, biomedical test structures, and the like. So there is a growing need for employees trained in cleanroom practices.
The two-credit elective, Semiconductor Processing Lab (MSE 447L/547L), is made possible through funds from the Intel-UA College of Engineering program in materials science and engineering. The lab opens up opportunities for internships and jobs in industries that value cleanroom manufacturing, and it makes graduate students more aware of research facilities and equipment.
“Many employers are impressed when they hear that a student has gone through formal training in fabricating structures in a cleanroom,” said materials science and engineering professor Srini Raghavan, who teaches the lab. “Students have an increased edge over their peers during the hiring process when they are properly trained in these types of procedures.”
The class is offered in the spring to students in all engineering majors and is preceded by a preparatory recitation (MSE\ECE 446\546) in the fall. Students in the lab learn how to gown up to work in cleanrooms and proper handling procedures for chemicals and materials inside a cleanroom, and they become familiar with various fabrication tools for micro and nano structures.
Engineering undergraduate student Diane Haiber said she now attends career fairs with an added level of confidence, thanks to the class.
“The course is structured so that students get hands-on experience through implementation of various fabrication and processing techniques: so far we have done wafer cleaning, thermal oxidation and photolithography,” she said. “And learning goes beyond the lab activities; Dr. Raghavan shares his own experiences from when he worked at Intel.”
Added graduate student Jivaan Kishore, “Not many universities offer such a comprehensive training program with respect to semiconductor processing.”
The class uses the only Class 10 certified cleanroom facility on campus, the Micro/Nano Fabrication Center, or MFC, housed in electrical and computer engineering.
The center’s manager, Omid Mahdavi, said the facility is a prime example of university-industry partnerships, one of the overarching themes in UA President Ann Weaver Hart’s recently unveiled “Never Settle” strategic plan.
“Most of the operational costs of running the MFC facility are covered by space and services offered to industrial clients who have on many occasions hired UA students,” said Mahdavi. “Here we have a lot synergy between academic and industrial activities. In a sense, President Hart’s Never Settle strategic plan has already been in motion here at the MFC for a number of years.”
The Micro/Nano Fabrication Center Lab in the ECE building is mostly a Class 100 facility and offers a limited Class 10 work environment. To put that classification in perspective, large semiconductor companies, such as Intel and Samsung, manufacture their products in Class 1 cleanrooms where there is no more than one particle the size of half a micron for every cubic foot of air. In contrast, the outside air generally contains more than 30 million particles of dust per cubic foot, which would equate to a Class 1,000,000 rating, also called room air.
The UA is home to two other cleanrooms: a Class 1,000 environment maintained by the chemistry department, and a Class 1,000 to 5,000 environment maintained by the College of Optical Sciences.

Engineering Week 2014 took place February 16-22, 2014 and at the UA, this culminated in an Egg Drop Contest on Friday, February 21st. A large number of College of Engineering students participated in the competition that involved vision, planning and team work. For the contest, students designed contraptions to house eggs with the goal of avoiding egg breakage during a drop from the AME building, and they were required to adhere to a set of rules that forbid the use of any parachute devices. No eggs survived the descent intact, but a number of groups were more successful with their egg conveyers than others and emerged victorious.
Second place went to representatives of the Society of Mining, Metallurgy and Exploration (SME) (pictured below).
Third place went to representatives of Tau Beta Pi (pictured below).
The contest started at MSE where students planned and designed their egg conveyance systems. Participating students then migrated to AME for the official egg dropping.
Do-it-yourselfers, roboticists, inventors, hobbyists, artists, bike modders, time lords, metalworkers, potters, hackers, steampunks, weavers, builders, woodcrafters, sculptors, tinkerers, programmers, car customizers -- all are welcome.
Student clubs from the UA College of Engineering will be turning out in force March 1 to support Tucson’s first maker festival, Maketopolis.
Students from the Baja, Formula, IEEE and video game developers clubs, plus UA-supported teams from the Tucson Pumpkin Toss and the Bitbuckets robotics club, will all pitch in to help put Southern Arizona's biggest maker fair firmly on the map.
Maketopolis is a daylong family-friendly showcase of Tucson's creativity, innovation and resourcefulness with something for everyone including rockets, robots, steampunk, 3-D scanning and printing, woodworking, quad copters, little free library boxes, electronics, welding, textile arts, LEDs, costuming, sugru, and polymer modeling.
The original Maker Faire, held in San Mateo, Calif., was launched in 2006 by Make magazine to “celebrate arts, crafts, engineering, science projects and the do-it-yourself mindset.” Since then, maker fairs have exploded in number in the United States, and become an international phenomenon, with fairs springing up in Europe, Africa, Australia, Canada, Scandinavia, and Singapore.
Maketopolis is an arts, crafts and technology happening that gives the entire Tucson community a chance to celebrate the do-it-yourself spirit of the maker movement. Artisans from countless disciplines will join together in Tucson’s diverse community and vibrant downtown to create a fun-filled day of demonstrations, conversations, and exhibitions that are certain to inspire both the beginner and the seasoned crafter to step out of the home workshop and to dive into the rich creative community in Tucson.
Beyond the fun and games, Maketopolis addresses issues that are critical to Arizona’s future, such as science, technology, engineering and math – or STEM – education, and workforce development and retention.
“Hands-on involvement in STEM activities is known to establish excitement and interest in the minds of young children and to provide relevance to what they learn in school,” said Patrick Marcus, president of Marcus Engineering, one of the event’s sponsors. “Maketopolis will stimulate this interest, as well as creating a dense community of collaborators and skill-sharing outside of the work environment, which will help retain our talented workforce and maintain a sense that there are many opportunities locally.”
Maketopolis is hosted by Xerocraft Hackerspace and Maker House in partnership with Gangplank Tucson, Startup Tucson, The Tucson Steampunk Society, BICAS, Sustainable City Project, UA Downtown, and the Pima County Public Library, and sponsored by Marcus Engineering and AGM Container Controls.
