| Summary: | This paper discusses a finite element analysis of a flat plate subjected to normal constant loading (cylinder-on-flat
configuration) with reciprocating sliding contact. The material properties follow a linear kinematic hardening plasticity model and the manipulated reciprocating tangential displacements are simulated for different sliding amplitudes, starting from 0.05 mm, 0.1 mm and 0.2 mm respectively. The predicted plastic deformation evolution on the contact region are reported for several parameters, i.e. equivalent plastic strain, tangential plastic strain, shear plastic strain tangential stress
and shear stress distributions. The effect of applied sliding displacement amplitude on stress and strain distributions is also investigated. The simulation results show that the stress distributions for kinematic hardening model are almost similar pattern for all three sliding displacements. The plastic strain distribution is proportional to the reciprocating sliding displacement amount, higher sliding displacement resulting higher plastic strain distribution. The trend of the plastic strain
distributions is increasing consistently when the sliding displacement varies from 0.05 mm, 0.1 mm and 0.2 mm. It is
found that the strain effect depends on the sliding displacement amplitude. |
