In this paper, a traction integral equation containing no hypersingular integrals is presented to study the interaction of multiple cracks in an infinite elastic medium. 8-node quadratic quadrilateral elements are used to discretize general crack surfaces, and special crack tip elements are employed

In linear elastic fracture mechanics (LEFM), Irwin's crack closure integral (CCI) is one of the sign&ant concepts for the estimation of strain energy release rates (SERR) G, in individual as well as mixed-mode configurations. For effective utilization of this concept in conjunction with the finite e
## Abstract For numerical analyses of fracture mechanics problems often a combination of the finite element method with a post processor program for the evaluation of Jβintegral values is used. Instead of calculating a line integral as originally proposed by RICE it is reasonable to evaluate surfac
