Abstract

The purpose of the work described was to investigate the contrast obtained in the reflection-scanning acoustic microscope from abrupt elastic discontinuities which are not parallel to the surface of the specimen. By way of introduction, images are shown in which reflection from the discontinuities gives rise to periodic interference. These show that such reflections have significant amplitude; and the periodicity enables the wave mode which is responsible to be deduced. A variety of experimentally obtained images is presented, which shows that enhanced contrast is found from surface-breaking cracks.
