... ). In the previous study [ 26 ], it was shown that a microdimple is produced in a bump located at the contact center, which is caused by the pressure difference within the bump and depends on the size and the shape of the bump. Furthermore, the bump is deformed by the pressure flow caused by the impact loading...
