As an exercise, consider doing a similar problem. This new problem pertains to two spheres in contact. Recalling that our example of sphere-to-plate used , the following example deals with two finite radii.
Compute the contact radius and compare with analytical results.
Compute the maximum pressure that is induced along the z-axis.
Check the validity of the numerical results by confirming the force reaction balance, and observe the effect of refining mesh.
