Effects of Diffraction on Stress Pulse Propagation.
Abstract
Investigations have been made of the effect of diffraction on the propagation of acoustic impluses in water. Gaussian shaped pressure pulses were obtained by applying 0.2 microsec wide voltage pulses to thick piezoelectric plates that act as piston sources. Acoustic probe techniques were used to examine in detail the resulting pressure pulses. These are strongly affected by diffraction phenomena and, because of the transient nature of the process, special care must be taken interpreting the observed data. Comparisons between experimental and theoretical time and space pressure profiles are presented. (Author)
