New Technique for Frictional Contact on Crack Slip in the Extended Finite-Element Method Framework

The traditional extended finite-element method (XFEM) encounters some challenges in the problems of frictional contact because the contact forces acting on the interface of cracks are difficult to determine. In this paper, a new method for the simulation for frictional contact on crack slip in the framework of the XFEM is proposed. Coulomb’s frictional model is introduced as the frictional constitutive model. The detection points are sowed on...
