Crack Study by Isogeometric Analysis Method

In this paper we enriched the isogeometric method for analyzing of structures with cracks ordiscontinuities. We take advantages of XFEM in modeling discontinuities and isogeometric inmodeling the geometry exactly and combined together. In this paper we prove The combinationof isogeometric analysis with XFEM produces high levels of accuracy with optimal convergencerates for linear fracture mechanicsThe results in numerical examples have been compared betweenthese methods. Also we analyzed curved crack with the acceptable accuracy.
