Stabilized finite elements for Tresca friction problem

06/23/2021 ∙ by Tom Gustafsson, et al. ∙ 0

We formulate and analyze a Nitsche-type algorithm for frictional contact problems. The method is derived from, and analyzed as, a stabilized finite element method and shown to be quasi-optimal, as well as suitable as an adaptive scheme through an a posteriori error analysis. The a posteriori error indicators are validated in a numerical experiment.
