Differential-Difference Iterative Domain Decomposition Methods for the Problems of Contact of Elastic Bodies with Nonlinear Winkler Surface Layers

We consider the problem of contact interaction several elastic bodies with nonlinear Winkler surface layers. To solve a variational equation nondifferentiable operator corresponding to this problem, we propose use implicit two-point combined differential-difference parallel iterative Robin-type domain decomposition algorithms. software realization these algorithms for case plane problems based on finite-element approximations. compare numerical efficiency and one-point methods two containing groove through layer.
