Parallel Solution of Elastoplastic Problems with Numerical Experiments
Original language description
In this paper we present efficient parallel implementation of solvers for elastoplastic problems based on the so-called Total Finite Element Tearing and Interconnecting (TFETI) domain decomposition method. We propose a set of numerical experiments to illustrate effectivity of the presented solvers. We consider an associated elastoplastic model with the von Misses plastic criterion and the isotropic or kinematic hardening law. The semi smooth Newton method is applied to solve this nonlinear system. Corresponding linearized problems arising in the Newton iterations are solved in parallel by the above mentioned TFETI domain decomposition method. The proposed TFETI based algorithm was implemented using PETSc and its performance is illustrated on a 3D elastoplastic benchmark. Numerical results for different scalability and mesh levels are presented and discussed.
