摘要

In the present study we describe the fini8te element formulation for problems with a crack to be embedded in the stiffer material in a structure consisting of two elastic isotropic materials. The cubic isoparametric singular element, represented by adequately shifting the mid-side nodes adjacent to the crack tip, is constructed to enclose the crack tip. An alternative method to obtain the optimal position of the mid-side nodes of cubic isoparametric elements is presented. In addition, a proper definition for the stress intensity factors of a crack normal to bimaterial interface is provided. The results obtained are compared with the previous solutions.
