MIPS Conference n°04 - Materials behavior: dissipative effects and thermomechanical couplings

The MIPS Research Cluster conferences are designed to raise community awareness of new topics and technological innovations.aimed at a wide audience - students, researchers of all disciplines - they feature the multidisciplinary expertise of the MIPS Cluster, partner clusters and structures, as well as national and international teams.They are held on the first Friday of each month at 11:30 a.m. and are followed by a buffet for further discussion.

Materials behavior: dissipative effects and thermomechanical couplings

The MIPS Cluster is pleased to welcome André Chrysochoos, LMGC researcher, for a lecture dedicated to the interactions between material deformation and associated thermal variations.When a material deforms, it often undergoes temperature variations, resulting from dissipative mechanisms (viscoplasticity, damage, cyclic fatigue...) or from interactions between its mechanical, thermal and microstructural states. Through practical experiments, numerical animations and experimental results, this lecture will illustrate the effects of dissipation and thermomechanical coupling, as well as the techniques used to measure these phenomena. The lecture will conclude with a presentation of a global thermomechanical framework, essential for the development of reliable behavior models, integrating both mechanical and energetic aspects.
