摘要：

This paper considers the effect of strain hardening on the elastic-plastic contact of a rigid ball with an elastic-plastic flat using experiments and finite-element software Abaqus. The strain hardening is an increase in the strength and hardness of the metal due to a mechanical deformation in the microstructure of the metal. Flat tensile samples with different values of strain are considered, in order to study the effect of strain hardening. It was found that the strain hardening phenomenon and anisotropy of both friction and material have a great influence on the ball indentation value and the maximum indentation force. The anisotropy of both material and friction conditions influenced the non-uniformity of the stress and strain distribution around the pin axis.
