Transient thermal stresses and thermal deformations of a semi-infinite solid cylinder with heated moving end surface. Effect of heat transfer on the end surface.

Abstract

This paper is concerned with a transient thermal stresses and thermal deformations of the axisymmetric problem of a semi-infinite solid cylinder on consideration of a moving boundary. Assuming that an end surface of the cylinder is heated with arbitrary relative heat transfer and moves with a constant velocity, the temperature distribution of the cylinder is analyzed using with a moving coordinate system. Thereafter, the associated thermal stress distributions and thermal displacements are determined with the aid of the thermoelastic potential function method and Love's displacement function method. As an illustration, numerical calculations are carried out for several velocity values of the moving boundary and the relative heat transfer coefficient of the heated end surface. The influence of the velocity and the heat transfer on the temperature, the thermal stresses and the thermal deformations are examined precisely.
