Description

The response of an elastic plate to sources of acoustic emission is a problem of current interest in the development of nondestructive inspection methods. So far the two main approaches that have been used to calculate the response are the ray theory and the normal mode technique. In this paper we present another method based on a classical integral transform technique. Working in the frequency domain, the spectral response is computed by summing the residues at the roots of the Rayleigh-Lamb spectrum. An FFT inversion gives the transient response of the plate.

Response of an Elastic Plate to Surface Loads and Buried Dislocation Sources

The response of an elastic plate to sources of acoustic emission is a problem of current interest in the development of nondestructive inspection methods. So far the two main approaches that have been used to calculate the response are the ray theory and the normal mode technique. In this paper we present another method based on a classical integral transform technique.
