Propagation of free waves in a composite plate with elastic coupling between the layers
The propagation of free waves in laminar plates and shells was considered in a refined formulation, when dynamic elasticity-theory equations are used to describe the layer motion. Two types of contact between the layers are analyzed here: rigid contact, when all the components of the displacement and stress are equal at the layer boundaries; and slipping contact, when there is no tangential stress at the boundaries. The problem in which the contact conditions are intermediate between these two ideal cases, i.e., in which the joint has some pliability, is of practical interest. For example, this situation arises in considering a composite material consisting of various glued layers, when it is necessary to take account of the pronounced pliability of this joint. In addition, investigation of an elastic joint may be useful in estimating the role of a thin soft layer between two more rigid layers.
