Thermal stresses in the refractory elements in the walls of an MHD channel
Abstract
A method proposed by Dubasov et al. (1973) for calculating the thermal stresses in refractory ceramic plates is applied to the determination of the thermal stresses in a simply supported cylinder of finite length in an axisymmetric stress-strain state. The temperature distribution in the cylinder is assumed to vary only in the vertical direction. The solution obtained is of importance in the analysis of thermal stresses in a refractory wall composed of ceramic elements. The solution is obtained as a sum of two solutions: that for the thermal stresses in a plate whose thickness is equal to the length of the cylinder, and the solution of the boundary value problem of the stresses in a cylinder to whose lateral surface the stresses determined from the first solution are applied with opposite sign.
