Abstract

This paper presents a review of several problems that arise from the mutual interaction of elastic waves and nonstationary temperature fields in solid continua. Particular attention is given both to uncoupled theories, where such interaction occurs as a result of the temperature dependence of the physical properties, and to coupled theories, where the temperature field is influenced by the time rate-of-change of the dilatation. Also discussed is the “second sound” effect: i.e., the conditions under which the finite propagation of heat pulses may become important. Throughout the paper, emphasis is given to relating the various phenomena which can occur, and on reckoning the magnitudes of the effects and the time scales which characterize various thermo-mechanical effects in elastic wave propagation.
