Abstract
Based on a sophisticated interface model a thermomechanical contact formulation is derived. The development addresses theoretical and numerical aspects. It starts from a continuous formulation of the local contact geometry and includes constitutive equations for the contact stresses, the contact heat flux and the frictional dissipation. Based on these considerations, a finite element model for large deformation processes is developed. An operator split technique concerning the solution of the global coupled equations is applied for the algorithmic treatment of the thermomechanical coupling. By means of three numerical examples, the theoretical and numerical formulations are validated.
