FORMULATION OF COUPLED PROBLEMS OF THERMOELASTICITY BY FINITE ELKMENTS

Abstract

When designing mechanical equipment, in numerous cases thermal effects have to be taken into consideration besides mechanical ones, especially if they are transient effects. In engineering practice these thermomechanical problems can be described by the different theories of thermoelasticity with adequate accuracy. This paper, after a brief survey of the basic equations of thermoelasticity, demonstrates its formulation by the finite element method.
