An efficient parallel solver for elasto-plastic problems of mechanics
Original language description
The goal of this paper is to present an efficient algorithm for the numerical solution of elasto-plastic problems in mechanics. These problems with hardening lead to the socalled quasistatic problems, where each nonlinear and nonsmooth time step problemis solved by the semismooth Newton method. In each Newton iteration we have to solve an auxiliary (possibly of large size) linear system of algebraic equations. In this paper, we propose a new approach how to solve such system efficiently using in a sense optimal algorithm based on our Total-FETI variant of FETI (Finite Element Tearing and Interconnecting) domain decomposition method. The efficiency is illustrated by the results of 3D elasto-plastic model benchmark. Civil-Comp Press, 2011.
