Application of Meshless Method to 2 dimensional crack propagation problem

Abstract

This paper describes an Application of Meshless Method to 2 dimensional crack propagation problem. The Meshless Method, it is effective method to apply to problem with complextive curved crack path, because the stiffness matrix obtained by estimate each nodes without element mesh. In this study, the local approximation is defined by using Taylor series expansion with high order derivatives, and Nodal Integration is evaluated by using Voronoi polygons.
