A finite deformation homogenization framework is developed to predict the macroscopic thermal response of contact interfaces between rough surface topographies. The overall homogenization framework transfers macroscopic contact variables such as surfacial stretch, pressure and heat flux as boundary conditions on a test sample within a micromechanical interface testing procedure. An analysis of the thermal dissipation within the test sample reveals a thermodynamically consistent identification for the macroscopic thermal contact conductance parameter that enables the solution of a homogenized thermomechanical contact boundary value problem based on standard computational approaches. The homogenized contact response effectively predicts a temperature jump across the macroscale contact interface.
