Some properties of the thermoelastic prestressed medium Green function
The dynamic coupled problem of excitation of harmonic oscillations on the layered prestressed thermoelastic body surface is considered. The body is under the action of the oscillating heat flow which is distributed on the surface in a certain region. It is a layer which is rigidly coupled to a half-space. The layer surface is assumed to be free from mechanical stress and outside the thermal stress region is thermal insulated. Thermal and mechanical effects induce initial stress state. The influence of different prestressing cases on the Green function poles distribution is investigated.
