Influence of Microstructural Parameters on Shape Memory Alloys Behavior
Abstract Modeling the functional behavior of material undergoing a martensitic phase transformation like in shape memory alloys is a challenge for the development of industrial applications using these materials. Multiscale modeling concepts developed in mechanics of materials are well adapted to solve this problem. Using a crystallographical description for the single-crystal behavior law, two examples of how the internal stresses influence the transformation in thin films and bulk materials are presented. Scale transition is performed with the self-consistent approximation in the bulk and with FEM in thin film.
