Multiscale materials modeling, and more precisely simulations at the mesoscopic scale, constitutes the most promising numerical framework for the next decades of industrial simulations as it compromises between the versatility and robustness of physically-based models, computation times, and accuracy.
The aim of this PhD is therefore to develop a FFT-based approach, suitable for large deformations. This approach should support our physical models of both discontinuous and continuous recrystallization. Particular effort will focus on reducing computation times, especially through FFT parallelization. The module will be integrated with existing tools at CEMEF.
