Numerical implementation of two nonconforming finite element methods for unilateral contact
The paper addresses the nonforming finite element approximation of unilateral contact between elastic bodies. As the meshes usually do not match, two methods of coupling the finite element meshes are investigated. One is a mortar-element type approach, the other uses explicit contact conditions between nodes and line-segments -- this only works in two dimensions. Error estimates for both approaches are given, the numerical matrix formulation is presented, and finally a numerical example comparing the two approaches is discussed.
