PLANAR HERTZ CONTACT WITH HEAT CONDUCTION.

The paper discusses the planar Hertz contact problem when the bodies are not only pressed together but also exchange heat by conductionXThe nature of the problem and the results depend strongly on the direction of heat flow'. If heat flows into the material with the larger distortivity, the common boundary conditions are sufficient to achieve a solution which satisfies the inequalities associated with a contact problem. For heat flowing in the opposite direction, the common boundary conditions by themselves lead to contradictions, but the difficulties can be overcome by introducing a zone of imperfect con\ taci^The formulation is based on a suitable Green's function, and the problem is reduced I to a singular integral equation which must be solved numerically.]
