MODELING OF DAMAGE EFFECT ON HEAT TRANSFER IN TIME-DEPENDENT NONHOMOGENEOUS SOLIDS

Abstract

This article demonstrates a concept of coupling between the heat transfer equation and the damage evolution in solids subject to creep at elevated temperatures. The second-rank damage tensor, which appears in the constitutive equations of creep and damage and, on the other hand, in the combined heat flow-radiation rule, plays a role of the variable introducing feedback. As examples, axisymmetric cylinders and disks subject to creep damage under combined mechanical and thermal loadings are considered
