Abstract：Based on thermomass theory, the temperature responses of a thin plate were investigated with the boundary subjected to sudden temperature rise. The heat conduction equation was established to describe the heat transfer along the thickness direction of thin plate by Newtonian mechanics. The temperature equation with differential form was obtained by combining with energy conservation equation. Laplace transform and inverse transform techniques were used to derive the analytical solutions of temperature distribution with the boundary subjected to uniform thermal shock. By the calculation of temperature field, the mechanism of heat transfer in thin plate was revealed. The results show that the thermal disturbance is generated in the boundaries of thin plate and deduces the propagation of two waves towards to the centre of thin plate with finite speed to form step temperature distribution. Affected by characteristic time and characteristic length, the speed of thermal wave shows dynamic distribution. The typical wavelike behavior of reflection and superposition is appeared to lead to the unnormal phenomena of extreme heat or cold.
