It is well known that slipping in automotive clutches is closely related to the concave deformation of the pressure plate. but the mechanism of this deformation is not clear. A simplified model of a pressure plate assembly is developed by simulating the deformation field of the plate under the condition of continuous sliding. followed by natural cooling to room temperature. https://www.roneverhart.com/Bioderma-Atoderm-Intensive-Gel-Creme-16-7oz/
