Abstract
The mechanism of permanent deformation of pressure plates has been investigated under very severe conditions, which are used for automobile clutches. Sliding tests were performed, where an extreme overload was applied to the pressure plate. It is found from the test results that the residual stress in the circumferential direction varied from compression to tension after the sliding test near the sliding surface of the plate. FE (Finite element) calculations were also conducted taking both plastic deformation of the plate due to thermal expansion and geometrical non-linearity into account. The FE calculations agreed well with the experimental results. The permanent deformation mechanism for pressure plates was summarized as follows. Compressive yielding of the plate occurs at the heating stage near the sliding surface. The residual stress in tension appears in the sliding surface when the plate becomes cool, and it deflects the plate like a bowl.
