摘要：
Ductile fracture using meshless Galerkin method is studied. We use well-known Gurson-Tvergaard-Needleman (GTN) in combination with visibility method. The GTN model is used in the bulk and when certain damage threshold is reached, discrete crack is introduced by taking advantage of the visibility method. The visibility criterion that modifies the particle connectivity based on evolving crack surface morphology is used. We demonstrate the applicability of meshless method to ductile fracture for several problems.
