I'm trying to simulate the stresses from pressing the edge of a square block on the surface of a plastic component. The stress results were about 50% different between the averaged and unaveraged results. I have refined the mesh to try bring this difference down, but the stress numbers only keep increasing and the difference doesn't reduce as the mesh count in the contact region is increased. Does this mean there is stress singularity arising from the sharp edge in contact with the cam? What would be a reliable method to simulate such contact problems? Kindly advise. Thanks!
