Grain scale modelling and parameter calibration methods in crystal plasticity finite element researches: A short review

Abstract

Crystalline material is commonly used in human society, crystal plasticity finite element (CPFE) method is an effective way to explore the grain scale thermodynamics behaviors of crystalline materials. In order to promote the development and application of CPFE method, this article briefly reviews grain scale microstructure modelling methods, grain scale constitutive modelling theories and grain scale constitutive parameter calibration methods used in recent CPFE works. Existing grain geometry modelling, polycrystalline microstructure modelling and multiphase microstructure modelling methods for crystalline materials were critically reviewed. Basic grain scale constitutive theories including single crystal elastic, single crystal plastic, grain boundary, damage and thermo-mechanic models were listed. Frequentlyused grain scale constitutive parameter calibration methods were summarized.
