A Brief Overview of Crystal Plasticity Approach for Computational Materials Modeling

AbstractThis article presents an overview of crystal plasticity (CP)-based modeling and simulation. A typical CP approach includes the kinematics and constitutive laws to determine the mechanical response of polycrystalline materials. Constitutive laws can be phenomenological or microstructure-based. The latter allows incorporating different deformation mechanisms responsible for deforming the material plastically. For solving the equilibrium and compatibility equations, the types of numerical solvers used are also discussed. For modeling the inhomogeneity in the polycrystalline and multiphase material systems, homogenization techniques are used in CP for the flow of information from single crystal to polycrystalline scale.KeywordsPlasticityConstitutivePhenomenologicalMicrostructureHomogenizationPolycrystalline
