Abstract

The use of numerical methods, particularly finite element methods in solving different problems are used in abundance. Because these methods are approximate, having a real understanding of the extent and distribution of the errors is extremely important. Studies show that the mesh used in the finite element method will be an essential error rate. So many different ways to find the optimal mesh and minimize the error of the proposed method. These methods are mainly aimed at reducing the error in the stress field have been obtained. Although one of the aims of reducing errors tension field finite element method is adaptive, but no guarantee is intended to achieve specific issues. These issues can be Craek to the issues noted in the analysis of the elastic parameters of the stress intensity factor will play a key role in determining the direction and Craek the design. The purpose of this study is to measure the stress intensity factor adaptive analysis on the parameter to be modified to accommodate ancillary parameters such as strain, stress intensity factor able to modify the target parameter
