A comparative study on the evolution of plastic zone between indentation and flattening contact

Abstract
The peak of the ratio between the average pressure to yield strength is called hardness. The average contact pressure of elastic–plastic flattening and indentation contacts is studied by using numerical simulation. The similarity and difference between the two kinds of single asperity contacts are investigated. This paper chooses five kinds of elastic–plastic materials as the deformable-body. The yield strength of these materials covers the typical steel materials range used in the engineering project. And the effect of the evolution of the plastic zone under the contact surface on the contact pressure distribution is analyzed. Before the elastic zone under the contact surface disappears completely, the evolution of the plastic zone of the two types of contact is similar. However, the average pressure of indentation contact continues to increase after this, until it reaches the maximum. The average pressure of flattening contact reached the plateau since elastic core has disappeared, and after a while, it began to decrease.
