Dynamic Growth of a Spherical Inclusion in Thermoelastic Medium


The paper deals with an initial value problem of dynamic uncoupled thermoelasticity concerning a moving spherical thermal inclusion in an infinite solid. An extended Kosevich' theory of continuously distributed defects due to prescribed plastic fields is used. Applying a generalization of the isothermal elastodynamics with continuosly distributed defects, the displacement and stress fields due to a spherical thermal inclusion growing linearly with time are obtained.
