Modeling Large Sliding Frictional Contact Along Non-Smooth Discontinuities in X-FEM

Seyed Mohammad Jafar TaheriMousavi and Seyedeh Mohadeseh Taheri Mousavi

Abstract—Modeling large frictional contact is a numerical tool to simulate abrasion resistant material. We have therefore proposed a new method to impose contact constraints in eXtended Finite Element Method (XFEM) framework. For this technique we impose penalty constraint on Node To Segment(NTS) elements. Moreover, the effect of friction has been investigated based on the Coulomb friction law. In our algorithm, new Lagrangian shape functions are proposed to solve the problems of the conventional Heaviside enrichment function. Finally, two numerical simulations for non-smooth constraints are delivered to show the efficiency of our algorithm.

Index Terms—Coulomb law, large sliding contact, non-smooth constraint, X-FEM.
