Dynamic response of an eight-ply composite plate to an impulsive line load (Q1184429)

The paper investigates the dynamic response of an 8-ply fibre-reinforced laminated plate to an impulsive line load acting on the upper surface of the plate. Each layer is modelled as a transversely isotropic elastic material for which the fibre direction is both inextensible and coincident with the axis of transverse isotropy. Within each layer an integral transform formalism and the propagator matrix method are used. The transforms are numerically inverted using the theory of residues. Numerical results are given. The results are shown at various interfaces throughout the laminate. The existence or non-existence of Rayleigh type surface waves is discussed.
