Modelling of Granular Fracture in Polycrystalline Materials Using Ordinary State-Based Peridynamics

An ordinary state-based peridynamic formulation is developed to analyse cubic polycrystalline materials for the first time in the literature. This new approach has the advantage that no constraint condition is imposed on material constants as opposed to bond-based peridynamic theory. The formulation...
