摘要

This study presents an ordinary state-based peridynamic model for ductile fracture analysis in 2D and 3D based on the von Mises yield criterion with isotropic hardening. A fracture model based on the critical bond stretch is employed as fracture criterion. The comparison between the experimental and the numerical results is presented and shows that the elastoplastic peridynamic model is capable to correctly reproduce the ductile fracture observed in the experiments.
