The problem of the nonstationary vibrations of an infinite elastic uniform thick plate resting on a thermoelastic isotropic half-space is solved. The equations of the plate motion take into consideration the rotary inertia and transverse shear deformations, and the half-space equations take the thermal flow lag into account. Both welded and smooth contacts between layer and half-space are considered. Nonstationary vibrations are excited by the instantaneous change in the ambient temperature above the plate to some magnitude that then does not change with time or by the instantaneous change in the plate temperature. The plate nonstationary vibrations, in their turn, give rise to three types of plane surface of strong discontinuity propagating in the thermoelastic half-space. The solution behind the wave fronts up to the contact boundary is constructed by virtue of ray series. Unknown functions entering into the ray series coefficients and into the equations of the plate motion are determined from the boundary conditions of the contact interaction of the plate and the half space. The time-dependences of the plate deflection and the plate temperature are obtained for both welded and smooth contacts. |
