On the Plate Velocity of a Generally Orthotropic Plate

The plate velocity for thin, isotropic, elastic plates (see Reference [1]) is a quantity which is useful for elementary analysis of wave propagation and as a normalizing factor for the analysis of dispersive type waves in plates and cylinders. Such a wave velocity expression for thin, anisotropic plates may find a similar usefulness and is derived in this note for a generally orthotropic, elastic plate with shearcoupling in the plane of the plate. For an off-angle orientation of the direction of
