Abstract: The finite element method is used to model large sliding frictional contact problems in which one body slides over another body and there is relative motion at the interface of the two bodies. The penalty approach has been used within finite element frame work to consider various constraints at the contact surface. The large sliding behavior between two bodies has been formulated by employing the node-to-segment (NTS) algorithm. The NTS technique searches for the active slave nodes and the corresponding master segments at the contact surface and then the contact stiffness matrix is evaluated to enforce the contact conditions. Finally, three problems are solved to demonstrate the applicability of the given technique in solving large sliding fictional contact problems. The given problems have been solved for both the frictionless contact as well as the frictional contact at the interface of the two bodies.
