Abstract

Following a recent participation in Sandia Fracture Challenge 2017, in which we identified some shortcomings associated with the peridynamic theory in predicting large deformation and ductile fracture, we recently proposed a bond-associated, semi-Lagrangian, peridynamic model that addresses the noted limitations. The new theory is employed to revisit the challenge problem. Our results show that the new approach significantly improves the predictions of ductile fracture phenomenon in this challenge.
