Some Aspects of Applying Finite Element Method to Contact Problems Using ABAQUS System

Authors: Ovchinnikova N. V., Chebotarevsky U. V.

In this paper the selection of preferred computational scheme for numerical research of a contact interaction between a rigid indentor andanelastic-plastichalf-spaceusing ABAQUS system is фdescribed. 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.

About Oblique Impact by Perfectly Rigid Body with Plane Boundary on the Nonlinear Elastic Half-Space

Authors: Dudko O. V., Potyanikhin D. A.

In this paper the impact interaction of perfectly rigid body and nonlinear elastic solid, which have plane boundaries, are investigated. Suppose that the moving rigid body has constant velocity, resulting in self-similar formulation of the problem. Possible variants of wave combinations, arising from such interaction, are discussed. The existence condition for evolutionary shock waves and the thermodynamic discontinuities compatibility condition serve as criterions for choosing the wave pattern.
