Abstract

A Newton-Krylov-FETI-DP method for solving problems in elastoplasticity is considered. In some cases additional coarse constraints are necessary to guarantee good convergence of the pcg algorithm. To enhance the coarse space in the FETI-DP method, we use a strategy introduced in Mandel and Sousedík (Comput. Methods Appl. Mech. Eng. 196, 1389–1399, 2007). We implement this method using a deflation approach.
