STEADY TIME-HARMONIC OSCILLATIONS IN A LINEAR THERMOELASTIC PLATE MODEL

We examine the bending of a Mindlin-type thermoelastic plate when the source terms are time-harmonic with angular frequency omega, and suffi cient time has elapsed for the system to have reached a steady-state, We show that in an infinite plate the solution can be represented as t he sum of five waves all but one of which exhibit damping, By formulat ing appropriate radiation conditions we prove uniqueness results for e xterior boundary value problems subject to certain regularity assumpti ons and a condition on the angular frequency of oscillation.
