Thermal Contact Conductance at Low Contact Pressures [PDF]
36th AIAA Thermophysics Conference, 2003 New correlations are presented for the truncated Gaussian (TG) thermal contact conductance model during first loading. The TG model is also incorporated into existing models for the hysteresis effect of thermal contact conductance and for the plastic contact pressure.
