This article provides a general review of fundamentals of crystal plasticity finite element method (CPFEM) and its application in simulating heterogeneous deformation in polycrystalline environment. CPFEM is an important simulation tool for microstructure-based mechanical process prediction, and engineering design involving anisotropic metal material media. Besides a brief discussion of the constitutive laws and kinematics of CPFEM, several of its applications in different deformation processes have also been reviewed, including the uniaxial tension of columnar-grain aluminum, the uni-axial tension of polycrystalline copper, and the four-point bending of polycrystalline titanium, etc. These simulations have all been compared with detailed experimental measurements to validate the accuracy of the applied model.
