Abstract:

Elastic stress waves propagating in thin, laminated composite plates are analyzed on the basis of a lamination theory based on the Kirchhoff assumptions, but including effects of shear deformation and rotary inertia. The individual layers comprising the plate are assumed to possess different thicknesses and material properties. Each layer may be arbitrarily anisotropic. Thus, a general coupling in shear, bending, twisting and extensional effects is present in the plate constitutive relations, resulting in simultaneously coupled stress waves propagating in the plane of the plate. Numerical examples involving laminated fiber-reinforced composite plates are presented.
