Abstract

Frequency spectra of transient Rayleigh-Lamb waves in a plate are evaluated by two methods, a direct numerical integration (FFT), and an asymptotic calculation of the theoretical responses. A simple formula is developed for the interference pattern of the spectra of two or more modes of progressing waves, which is then applied to interpret the complex frequency spectra of the waves in a plate over a wide range of frequency. These interpretive techniques may be applicable to source characterization of acoustic emission.
