Abstract:
Mortar finite element methods allow for a flexible and efficient coupling of arbitrary non-conforming interface meshes and are meanwhile quite well-established in nonlinear contact analysis. In this paper, a mortar method for 3D finite deformation contact is presented. Our formulation is based on so-called dual Lagrange multipliers, which in contrast to the standard mortar approach generate coupling conditions that are much easier to realize, without impinging upon the optimality of the method....     »
