OSCILLATION PROBLEMS IN THIN PLATES WITH TRANSVERSE-SHEAR DEFORMATION

In this paper, the authors present a modern theory of thin elastic pla tes with transverse shear deformation where the disturbance is represe nted by a train of harmonic waves. Dirichlet- and Neumann-type problem s are formulated together with appropriate radiation conditions (in th e case of the exterior domain). The paper shows that uniqueness for ex terior problems is guaranteed fora range of flexural waves. In the int erior problems, the presence of eigenfrequencies means that there is n o general uniqueness result. The paper also indicates how correspondin g results can be proved for micropolar plates.
