Axisymmetric Contact Analysis
Press- or shrink-fitting techniques are applied in various mechanical or forming components for the purpose of joining different components (for instance a shaft with sleeves or gears). Pre-stressing is used for forging or drawing dies in order to prevent excessive tensile hoop stress which causes their failure. It is important to be able to calculate accurate contact tractions for their design. Many of these components have an axisymmetrical geometry and in this case Lamé analytical formulae  can be applied only for the infinite long rings subjected to uniform internal and external pressure.
