MIPS Conference No. 04 – Material behavior: dissipative effects and thermomechanical couplings

The Research Cluster conferences aim to raise awareness within the community about new topics and technological innovations.Intended for a wide audience—students and researchers from all disciplines—they draw on the multidisciplinary expertise of the MIPS Center, partner centers and organizations, and 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 lunch, providing an opportunity for further discussion.

Material behavior: dissipative effects and thermomechanical couplings

The MIPS Center is pleased to welcome André Chrysochoos, researcher at LMGC, 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, etc.) or interactions between its mechanical, thermal, and microstructural states. Long neglected, these thermal variations nevertheless play a key role in the behavior of materials and the modeling of their evolution.Through practical experiments, digital animations, and experimental results, this conference will illustrate the effects of dissipation and thermomechanical coupling, as well as the techniques used to measure these phenomena. The presentation will conclude with a presentation of a global thermomechanical framework, essential for the development of reliable behavior models, integrating both mechanical and energy aspects.
