After the Second World War, Non-traditional heat transfer effect, which is possible to appear in rapid transient heat transfer process is gradually growing into a new research focus due to its great practical potentiality and academic significance, with the rapid development of the fire science,heat energy power, nuclear power, mechanical manufacture, chemical industry, high speed aeroplane, space navigation and rocketry.This paper have studied on the one dimensional strong transient heat conduction problem in a rapidly heated thin plate which is in the second kind boundary condition. The paper obtains the analytical solutions of temperature field by using the hyperbolic heat conduction model. Then paper compares the hyperbolic analytical solutions with the analytical solutions obtained from the parabolic heat conduction model.Moreover, based on the theory of thermoelastic mechanics,this paper studyies the distribution of thermal stresses in the thin plate supported simply in the temperature field determined in this work.At last, for the purpose of revealing the thennoelastic coupling character of rectangular plate, this paper discusses in detail the thermal shock of the rectangular plate that is subjected to heat on the top side,heat insulation on the bottom side, isothermal temperature on the four flanks,and that is simply supported on the four sides.From the finite work of author,the purpose of this paper is questing about the law of transient heat conduction and the distribution of thermal stresses of the model described in this paper in the second kind boundary condition. So that this paper can obtain some valuable conclusions, and provide the practical engineering with some data referenced worthily.
