DYNAMIC-RESPONSE OF THICK ANISOTROPIC COMPOSITE PLATES

We develop the analysis and numerical calculations for the response of thick anisotropic elastic plate strips subjected to transient loading s. This analysis encompasses a wide variety of laminated fibrous compo site models having multioriented layers. The analysis is conducted in two steps. In the first step, the characteristic free vibrational mode s of the plate strip are derived. Here, linear transformations are uti lized to handle the anisotropic behavior. In the second step, the appl ied loads are expanded in terms of the normal modal functions and the response of the plate is obtained by superposition of the appropriate components. Numerical illustrations are given in the form of dispersio n relations and space variations of the response for a representative loading situation.
