Abstract

In the present study the software CrackComput, based on the Xfem and Xcrack libraries has been used for three problems- to experiment on the convergence properties of the method applied to elasto-statics crack problems, comparison of stress intensity factors to simplified analytical results and study of the Brazilian fracture test. All the problems are treated in two dimensions under plane strain assumption and the material is supposed elastic and isotropic. For the first example, comparison for different parameter-enrichment type and radius, degree of polynomial has been performed. Second example convergence of SIF with the L/h ratio has been performed and compared with the analytical solution. Third example is the study of snapback phenomenon.
