The present paper is concerned with spherically symmetric thermo-elastic wave propagation without energy dissipation in an unbounded elastic medium with a spherical cavity. The inner boundary of the cavity is subjected to a unit step in stress and a zero temperature change. Short-time approximations of the solutions for displacement, temperature and stresses are given. The Laplace Transform is applied...
In the present paper, the generalised theory of thermo-elasticity proposed by Lord and Shulman [1] is applied to study the spherically symmetric thermo-visco-elastic wave propagation in an infinite isotropic visco-elastic solid of Kelvin-Voight type, with a spherical cavity. The inner boundary of the cavity is subjected to a unit step in stress and a zero temperature change. The distributions of temperature,...
