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.
The USIF Scanning Electron Microscopy (SEM) Workshop Series is a one-day workshop that will be held Thursday, August 21st, 2014 to support training on the Hitachi S-3400 and Hitachi S-4800 SEM. The workshop includes a review of basic instrument principles, operations, and parameter adjustments; a discussion of the effects of changing parameters on image quality; and an overview of the software available. The SEM workshop is open to all UA students and researchers who will be using SEM for their research projects. This workshop is provided free of charge, and the deadline to apply for the course is Thursday, August 14th at 5pm. Please RSVP to email@example.com.
Preliminary Program (Location TBD)
Lecture: 9-12 am Basic SEM & High Resolution
Lecture: 1-2:30 am EDS and Elemental Analysis
Lab: 2:30 – 4:30 pm

In 2012, University of Arizona, through engineering associate professor Ricardo Valerdi, partnered with the Arizona Diamondbacks to create The Science of Baseball, an academic curriculum for middle school students that promotes real-world applications of science, technology, engineering and math principles (STEM). To date, the program has reached 100 Arizona schools and 2,000 students across the state.
Now, with the goal of rapidly expanding the reach of the innovative curriculum, the University of Arizona has licensed the rights to the innovative STEM curriculum to Science of Sport, a new company founded by Valerdi, former UA Medical Center Director of Community Relations Crystal Kasnoff, and former San Diego Padres President/CEO Ballard Smith.
Tech Launch Arizona, the unit of the UA that helps faculty members commercialize inventions arising out of their research, facilitated the formation of the new company and the licensing of the intellectual property.
While the Arizona Diamondbacks maintain the rights to distribute the curriculum within the state, the new company aims to deliver the innovative teaching and learning materials via professional sports teams across the nation, and potentially to young sports fans around the world.
“Step one is to be in 30 major league baseball cities and be in every middle school in each market,” says Smith. “Those 30 teams combined have 100 minor league teams in 100 other cities.”
Beyond the US, they have already run Science of Baseball camps in Australia and are targeting Mexico in 2015, according to Valerdi.
To pay for the program, Science of Sport – a not-for-profit company – solicits funding from major league teams, foundations, state and federal programs, corporations and school professional development funds. That money is used to put on STEM camps where students work through the curriculum. Schools and teachers also learn how to implement the program via “train-the-trainer” models. The company plans to target communities with professional sports teams, but focus specifically on those where it can most effectively reach disadvantaged student populations.
Science of Sport already has a contract with the Los Angeles Angels of Anaheim, whose program will start later this month.
“We’ve had serious discussions and negotiations with the Red Sox, the Nationals and the Padres,” says Valerdi. “We just had a conference call with the Mets, and have a meeting set up with the Dodgers.”
According to Smith, “We have met numerous times with these teams and with the school districts in those markets, and everyone is enthusiastic about the program.”
The curriculum uses the principles of baseball as content for the exploration of topics in biology, mathematics and physics. It directly supports STEM initiatives by focusing on the Common Core Mathematics Standards that have been adopted by a majority of the states in the U.S.
According to UA Director of Technology Transfer Doug Hockstad, “Getting young people involved in the STEM disciplines early is one of the great challenges of education. This program, having been proven to be effective in Arizona, represents a fantastic opportunity engage many students in communities around the nation.”
While baseball will be the initial focus, over time Science of Sport plans to expand the curriculum to other sports such as football, basketball and soccer, with the goal of bringing STEM education to young sports fans everywhere.
