A finite element approach, based on the concept of the J,-integrals, is derived for evaluations of the ERR associated with crack kinking in 2-D elastic anisotropic solids. The application is developed as a generalized version of the domain integral method. Attention in this work is also addressed to
A simple numerical method which allows calculation of Mode I stress intensity factors is presented. Using a linear extrapolation of the energy release rate 9, as calculated using standard nonsingular isoparametric elements and a relatively course mesh, accuracies of better than 5% may be obtained.

## A finite element based crack-closure integral for determining strain energy release rates for two-dimensional elastostatic and elastodynamic crack problems in finite bodies is evaluated. Both the J-integral and crack-closure integral are used to obtain strain energy release rates from the finit
The approximate energy release rate for a crack which extends, or "kinks", away from its original direction has been computed by finite element analysis using three different methods: stiffness derivative procedure, J integral method and crack closure integral procedure. A case study is presented to
