Abstract

Authors have explored the wave phenomena generated by a Gaussian P-beam input into an aluminum plate. Extensive numerical calculations have been carried out in order to gain quantitative understanding of how different choices of parameters affect the response. The rapidly established oscillatory forms can alternatively be interpreted by interference between a group of modes surrounding the one most favored by the incident beam spectra. The P-plane wave constituents in this favored mode have a spectral angle closely aligned with that of the incident beam axis, and the period of its oscillations closely matches that in the observed pattern. The understanding gained from the present study has influenced substantially the choice of beam parameters, etc., leading to a good interaction with the flaw as well as a good parametrization of the resulting displacements observed on the plate surface.
