Mortar finite element methods allow for a flexible and efficient coupling of arbitrary nonconforming interface meshes and are by now quite well established in nonlinear contact analysis. In this paper, a mortar method for three-dimensional (3D) finite deformation contact is presented. Our formulation is based on so-called dual Lagrange multipliers, which in(More)
The objective of this work is the development of a novel finite element formulation describing the contact behavior of slender beams in complex 3D contact configurations involving arbitrary beam-to-beam orientations. It is shown by means of a mathematically concise investigation of well-known beam contact models based on point-wise contact forces that these(More)
