The influence of both full stick and perfect slip contact conditions on the unloading and multiple loading of a deformable sphere by a rigid flat is investigated using the finite element method for various values of the Poisson’s ratio and the modulus of elasticity over the yield strength ratio. The residual deformations and stress field within the sphere tip, as well as changes in the size of the contact area following multiple loading cycles are analyzed.
