Enriching mean-field self-consistent texture simulations using the full-field FFT model

Abstract

In the present work, crystal plasticity simulations using the fast Fourier transform (FFT) based Düsseldorf advanced material simulation kit (DAMASK) are performed to provide new insights on choosing the value of interaction parameter in the localisation equation of the visco-plastic self-consistent (VPSC) model. A statistical criterion based on the distribution of shear rates at each material point is obtained using DAMASK, which enables the judicious selection of the interaction parameter in the VPSC model. Subsequent large-scale texture simulations via VPSC indicated an excellent match between experimental and simulated textures, which establishes the effectiveness of the proposed approach of learning from full-field models and using it in the mean-field, less computationally expensive VPSC model for performing efficient texture simulations.
