In this paper thermally induced small amplitude vibrations of a moderately thick, layered plate with polygonal planform are investigated. The considered plate is composed of three dissimilar linear elastic homogeneous layers in perfect bond, which are asymmetrically arranged. The Mindlin-Reissner kinematic assumptions are implemented layerwise, and as such model both the local and the local response. For a plate composed of layers with a uniform ratio of mass density to shear modulus and a common Poisson's ratio the lateral deflection can be calculated independently from the in-plane displacements. It is shown that the lateral deflection is governed by a boundary value problem of the fourth order. Alternatively, by neglecting the longitudinal as well as rotatory inertia the complex problem reduces to the simpler case of a homogenized shear-deformable plate with effective stiffness, a corresponding set of boundary conditions and effective thermal strain resultants.
