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.
