Transient thermo-mechanical contact between a sphere and a moving flat is investigated using finite element analysis. Both the sphere and the flat are treated as elastic plastic bodies with isotropic hardening. Friction is related to heat generation at the contact interface. Strain and temperature distributions of the contacting bodies are obtained. For conditions corresponding to contact between a slider and a disk in a hard disk drive, plastic deformation and high temperatures are found to occur at the interface.
