✦ Synopsis

The equation of material momentum, or pseudomomentum, is obtained for thermoelastic materials. This is done in the classic theory, based on the heat conduction hypothesis, and also in the framework of a thermoelasticity approach involving no dissipation of energy, as recently proposed by Green and Naghdi. The results are applied to the thermoelastic fracture problem. When the pseudomomentum equation is written in global form, for a fractured body, it provides path-domain invariant expressions for the thermoelastic energy-release rate.
