Indentation Problems, the stress field and the force–displacement relation are defined by the Hertzian analysis. The maximum shear stress associated with the axisymmetric Hertzian problem occurs at a depth of 0.48., where . is the radius of the contact circle and this point reaches both the Tresca and von Mises yield co

Thermoelastic Contact,ic deformations, though generally small, can therefore have a major effect on systems involving contact. Further interesting effects are introduced if the thermal boundary conditions at the interface are influenced by the mechanical contact conditions. The thermal and thermoelastic problems are then

The asymptotic elastic fields at the boundaries between these regions generally exhibit singularities, either in the stresses or in the stress gradients, and the properties of the corresponding singular fields often lead to results of some generality. For example, we can show that in an
