Extended Finite Element Method for Crack Propagation

ISBN: 9781848212091 出版年：2013 页码：280 Sylvie Pommier Anthony Gravouil Wiley

Novel techniques for modeling 3D cracks and their evolution in solids are presented. Cracks are modeled in terms of signed distance functions (level sets). Stress, strain and displacement field are determined using the extended finite elements method (X-FEM). Non-linear constitutive behavior for the crack tip region are developed within this framework to account for non-linear effect in crack propagation. Applications for static or dynamics case are provided.
