Biography
Jean-Michel Scherer is a researcher specializing in materials mechanics and the numerical modeling of the mechanical behavior of solids. His work focuses primarily on crystalline plasticity, ductile and brittle fracture, as well as size effects and localization phenomena in metallic materials. He has contributed to the development of advanced constitutive models incorporating multiscale approaches, such as the plasticity of single crystals and polycrystals, strain gradients, and the mechanisms of void nucleation, growth, and coalescence. His research also explores the influence of microstructures, boundary conditions, and material parameters on the formation of strain patterns and crack propagation, using numerical methods such as the finite element method (FEM) and fast Fourier transform (FFT) simulations. His expertise includes the thermodynamic formulation of models, their numerical implementation, and their validation through comparison with experimental data or reference simulations.

Teaching
Mechanics of Continuous Media
In-person instruction is structured around plenary sessions in the lecture hall and tutorial sessions (PC) in smaller classes with fewer students. Independent work consists (in addition to the engine disassembly and reassembly activity mentioned above) of studies conducted individually or in small groups: work based on course materials (handouts, textbook), and solving two problems selected from an extensive list of highly varied problems (as mentioned above; see details below).
