The new energy release rate equation for the crack problem with centrifugal loads is presented. Using the concept of the shape design sensitivity, the final analytical equation is derived by the energy principle and the material derivative. Any numerical tool such as the finite element method can be

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 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 strain energy release rate for a crack at the interface of dissimilar isotropic materials was derived from an existing crack tip field. In the derivation, the J-integral along a special near tip contour was used. A single expression of the strain energy release rate corresponding to different de
