Abstract

The purpose of this paper is to propose a set of algorithms that can be used to develop an automated crack-tip finite element mesh for numerical fracture mechanics analysis. The algorithms were developed in MATLAB based on a two-dimensional boundary layer formulation. It was further shown that the nodes and elements of the models can be numbered in a consistent pattern by controlling the order of generating the nodes and the elements in the models. It was also demonstrated that the nodes can be connected in a systematic order to form second order quadrilateral element using the proposed algorithms.
