Some aspects of applying finite element method to contact problems using ABAQUS system

In this paper the selection of preferred computational scheme for numerical research of a contact interaction between a rigid indentor and an elastic-plastic half-space using ABAQUS systemis described. Furthermore, the critical values of the load applied to indentor which don't cause plastic deformation in the material and subsequently don't effect the process of a surface hardening are determined. Some peculiarities of the forming of near-surface plastic region by static loading are investigated.
