Thermoelastic contact problem of two rotating bodies with frictional heat generation in annular region

Summary An axisymmetric contact problem with frictional heating is considered in which a parabolic annular punch is pressed into a plane surface and rotates about its axis of symmetry at constant speed. The problem is formulated in terms of one governing equation with unknown pressure. This equation is solved numerically. The change of the geometry of the contact region and pressure has been investigated. Received 21 May 1997; accepted for publication 23 June 1997
