A new unsteady-state method that determines thermal contact conductance, or resistance, between two solid materials in contact with each other is presented. The feature of this method is that it enables conductance to be determined by applying an arbitrary-functioned heat input to the specimen. The general measurement principle of the method is derived for systems of one-dimen-sional rectangular coordinates. The principle utilizes the Laplace transform of the heat conduction equations for two materials and the continuity equation of the heat flux at the interface. The equation for determining conductance involves the Laplace integral values of the temperature responses measured at two positions in each sample. A series of numerical simulations is performed to evaluate the measurement errors of this method. Experimental study is performed to verify the validity and usefulness of the method.
