Simulation of micromechanical behavior of polycrystals: finite elements versus fast Fourier transforms
2009
Modelling and Simulation in Materials Science and Engineering
In this work, we compare finite element and fast Fourier transform approaches for the prediction of the micromechanical behavior of polycrystals. Both approaches are full-field approaches and use the same visco-plastic single crystal constitutive law. We investigate the texture and the heterogeneity of the inter-and intragranular stress and strain fields obtained from the two models. Additionally, we also look into their computational performance.
