Mechanical Metrics of Virtual Polycrystals (MechMet)
Source abstract
Abstract
The details of polycrystalline microstructure often influence the early stages of yielding and strain localization under monotonic and cyclic loading, particularly in elastically anisotropic materials. A new software package, MechMet (mechanical metrics) provides a convenient finite element tool for solving field equations for elasticity in polycrystals in conjunction with investigations of microstructure-induced heterogeneity. The simulated displacement field is used to compute several mechanical metrics, such as the strain and stress tensors, directional stiffness, relative Schmid factor, and the directional strength-to-stiffness ratio. The virtual polycrystal finite element meshes needed by MechMet can be created with the Neper package or any other method that produces a 10-node, tetrahedral, serendipity element. Formatted output files are automatically generated for visualization with Paraview or VisIt. This paper presents an overview of the MechMet package and its application to polycrystalline materials of both cubic and hexagonal structures.
