Conference paper


For the stable numerical solution of nonlinear elastodynamic contact problems implicit discretization schemes are required. Here, we discuss a temporal discretization scheme where in each time step spatial displacements are computed as the solution of an optimization problem allowing for the application of globalization strategies. Moreover, in order to treat the solution of these optimization problems more efficiently, a novel abstract nonlinear preconditioning framework for globalization strategies is presented.
