    • Thermal contact resistance in a non-ideal joint 

      Roca, Richard T.; Mikic, B. B. (Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1971], 1971)
      The contact conductance at an interface can be determined by knowing the material and surface properties and the interfacial pressure distribution. This pressure distribution can be influenced strongly by the roughness of ...
