Transient Thermal Stress Problem in an Infinite Circular Cylinder : The Heat-Transfer Coefficient Depends on a Position

Abstract

This paper deals with a transient thermal stress problem in an infinite circular cylinder whose the heat-transfer coefficient depends on a position. The finite difference method is used with respect to a time variable, because of difficulty in obtaining the analytical expression. Thus, the analytical expression with respect to the spatial variables may be obtained. The temperature solution is reduced to solution of a dual-integral equation. The numerical results of the effect of variation of the heat-transfer coefficient as to a position on thermal stresses are shown in figures.
