The Contour Integral Method for Loaded Cracks
نویسنده
چکیده
An extension of the contour integral method (CIM) for the computation of stress intensity factors for loaded cracks is presented. Numerical solutions of the two-dimensional linear elasticity equations are computed with the p-version of the generalized finite element method. Polynomial enrichment functions as well as enrichment with near crack tip asymptotic expansion are used. The robustness of the formulation with respect to the size of the extraction domain and the convergence of the computed stress intensity factors and energy release rate are analyzed. keywords: Stress intensity factors, loaded cracks, contour integral method, generalized finite element method.

In this paper, the plates made of functionally graded material (FGM) with and without a crack are numerically simulated, employing the finite element method (FEM). The material property variations are defined to be fully continuous; therefore, the elements can be as small as required. For this purpose, variations of the material properties are applied in both the integration points and in the n...
