Wave Propagation in Laminated Composite Plates,

Abstract

A stiffness method has been used in this paper to study dispersive wave propagation in a laminated anisotropic plate. The advantage of this method is in its usefulness in obtaining numerical results for the dispersion characteristics of waves propagating in a plate with an arbitrary number of arbitrarily anisotropic laminae. We have applied this method here, as a way of illustration, to plate made up of transversely isotropic laminae with the axis of isotropy of each lamina lying in the plane of the lamina. Results thus obtained are shown to agree well with the exact solutions for isotropic and transversely isotropic single layered plates. We present numerical results for cross ply laminated composite plates and show that the frequency spectrum in this case differ considerably from that for a single layered plate.
