Unified primal-dual active set method for dynamic frictional contact problems

Abstract In this paper, we propose a semi-smooth Newton method and primal-dual active set strategy to solve dynamical contact problems with friction. The conditions of Coulomb’s friction can be formulated in the form fixed point problem related quasi-optimization one thanks method. This is based on use (PDAS) strategy. main idea here find correct subset $\mathcal{A}$ A nodes that are (active) opposed those which not (inactive). For each case, nonlinear boundary condition replaced by suitable linear one. Numerical experiments both hyper-elastic rigid granular materials presented show efficiency proposed
