Solving elastoplastic problems with different preconditioners
Original language description
This paper illustrates the parallel solution of elastoplastic problems with hardening based on the TFETI (Total Finite Element Tearing and Interconnecting) domain decomposition method with preconditioning. We consider time step problems formulated by nonlinear variational equations in terms of displacements. To treat nonlinearity and nonsmoothness we use semismooth Newton method. In each Newton iteration we have to solve linear system of equations and for its numerical solution we use TFETI domain decomposition method with preconditioners (Dirichlet and lumped). We demonstrate our approach on von Mises plasticity with isotropic hardening using the return mapping concept for one time step.
