STATIC AXISYMMETRICAL HERTZIAN CONTACTS SUBJECT TO SHEARING FORCES

A numerical method is used to resolve the classic Mindlin-Cattaneo par tial slip problem for contact between similar and between dissimilar b odies. It is shown that, for similar bodies, the surface frictional en ergy dissipation is concentrated off the plane of symmetry although th e overall dissipation is similar to that predicted by the classical so lution. This effect is enhanced for certain combinations of dissimilar materials, where the process of frictional shakedown leads to a displ aced contact and hence additional shear compliances.
