Validation of a Multiscale Modeling of Thermomechanical Behavior of Shape Memory Alloys thanks to in-situ X-Rays Diffraction
Résumé
Recently, a multiscale and multiaxial model has been built, that describes the behavior of a RVE from the physics of martensitic transformation and R-phase transformation on the scale of the crystal lattice. It is based on the comparison of the free energies of each component. A probabilistic comparison is made (Boltzmann distribution) to determine the internal variables: the volume fractions of the phases. This model simulates of all kinds of thermo-mechanical loading for both isotropic and anisotropic textures and gives account for the behavior properties of SMA
