Multiple reflections of Lamb waves at a delamination [PDF]
Ultrasonics, 2002 Wave propagation in laminated plates with delaminations was calculated using the semi-analytical finite element method. The visualization results and deeper numerical analyses revealed the following phenomena on the fundamental Lamb modes at delamination regions of laminated plates.

Subsonic Lamb waves in anisotropic plates [PDF]
Quarterly of Applied Mathematics, 2002 A six-dimensional complex formalism for analysis of Lamb waves propagating with subsonic speed in anisotropic plates is formulated. Conditions for nonexistence of certain Lamb waves in anisotropic plates are obtained. An example of a transversely isotropic plate having “forbidden” speed at which no subsonic Lamb wave propagates is presented.
