Modeling of Single‐Slip Finite Strain Crystal Plasticity via the Virtual Element Method

Abstract

AbstractThis work addresses an efficient low order virtual element method (VEM) for the modeling of single‐slip crystal plasticity system undergoing finite deformations. VEM has been attracting attention as a novel scheme within the field of computational mechanics. A key advantage of VEM is the ability of constructing an arbitrary element shapes that can be non‐convex [1]. Another important aspect is that VEM fits the grain shapes of crystal plasticity within polycrystalline aggregates perfectly. Contrary, classical finite element (FE) approaches request a fine mesh‐size at possibly sharp geometric regions, i.e. complex shaped grain boundaries.
