Pulse propagation in plate elements

This paper describes a theoretical and experimental study of pulse propagation in plates. Specifically, this approach uses the Fourier–Laplace Transform (FLT), for the solution of the Lame equation with the boundary condition given by the transducer over one side of the plate. It is shown that a pulse in plates is formed by three fundamental components with its own dispertion relationship. Experiments were performed in elastic plates to validate the model.
