Comparison of computationally predicted contact pressures (MPa) distributed along the edge on the cup rim for three representative mesh densities with the element sizes of 0.5, 0.25 and 0.0125 mm, as a result of head lateral displacement of 0.5 mm under a load of 0.5 kN (a). The contact pressure distribution along the edge (approximately 3 mm in length) for the mesh with the element size 0.0156 mm, and a close view of the distribution for the first quarter length as highlighted (b).
