Figure 1 shows an elastic cylinder pressed onto a rigid foundation. The rigid foundation is constrained in all directions. The cylinder is constrained in the horizontal direction along the inner edge to simulate the behavior of a half cylinder. The results are obtained for three load values; F = 25, 50, and 100 N. Geometric nonlinear analyses are carried out to determine the contact pressure along the contact interface, and the results are compared with the theoretical solution.
