Biography

Charles-André GANDIN is a CNRS researcher specialized in modeling of solidification of metallic alloys. His work focuses on the thermomechanical and microstructural analyses , particularly through coupling of approaches such as Cellular Automaton (CA) and Finite Element (FE) methods. He has contributed to the development of predictive models to simulate grain structure formation, residual stresses, and distortions in processes such as laser powder bed fusion (L-PBF), wire laser additive manufacturing (WLAM), ingot casting, continuous casting, investment casting, … His researches also address the influence of process parameters on the mechanical properties of materials, such as nickel-based superalloys (single crystal alloys) and stainless steels (316L), by integrating models of crystal plasticity and multiscale analyses. His recent work includes the modeling of non-equilibrium phase transformations and its consequences on the formation of defects in solidification microstructures.
