Transient Thermal Stress Analysis in Stratified Insulating-Refractory Materials

Abstract

The transient thermal stress in the insulating-refractory materials made by stratifying two kinds of materials which have different fire-resisting properties and thermal resistances was theoretically analyzed by the finite element method on the basis of plane strain model. The measured values for the transient temperature profile in sample and the strain and the tensile stress at the outer surface of sample were found to be in fairly good agreement with predicted values by the proposed analytical method.
