Abstract : A number of studies related to structural dynamic behavior of laminated orthotropic plates and shells is reported. The plate or shell structure is composed of an arbitrary number of bonded elastic orthotropic layers, whose principal elastic axes coincide with the coordinate axes. These studies are based on two main approaches to the problem such as formulations by shell theory and by linear elastic theory. Generally, shell theory formulations are approximate by virtue that they take special note of the structural geometry and the anticipated deformation characteristics into account in order to arrive at simplified governing equations appropriate for a large class of shell configurations. The role of an elasticity formulation, aside from its inherent capacity to predict frequencies, stresses and deformations over a wide range of wave lengths, is then to delineate the limits of applicability of shell theory formulations.
