Implementation of Domain Integral Approach for J Integral Evaluations

摘要

This paper presents an implementation of the Domain Integral Approach for calculation of the J integral. Thernmethod has been programmed by way of a series of sub-routines of the ANSYS Finite Element program, using itsrninternal APDL programming language. This allows the J integral to be calculated by post-processing the results of arnstress calculation from the program itself. Also analyzed are the results of application to specific cases, includingrncomparisons with the results obtained by applying other methods to these same cases.
