Abstract
This study concerns the prediction of crack propagation topography in isotropic materials under cyclic loading by using peridynamics. Crack growth and its topography are governed by a single failure parameter referred to as critical stretch through an unguided process. The critical stretch can be expressed in terms of the fracture toughness of the material. Three dimensional simulations concern the propagation of a quarter corner crack and a circular surface crack in a beam subjected to cyclic four-point bending loading. The simulations capture experimentally observed non-self-similar crack propagation topography.
