Micro Abstract:
A two-scale, finite element (FE) and fast Fourier transform (FFT) based thermo-mechanically coupled material model formulation is proposed. The method is developed for the prediction of the structural material behavior and the corresponding local fields of viscoplastic polycrystalline materials. It allows for a qualitative investigation of the microscopic interplay between stress and temperature induced martensitic phase transformation and plasticity.
