Abstract

The generation of elastic volume waves by a source which is widely used in acoustic flaw detection is considered. This source produces normal stresses at the boundary of an elastic solid. The source is large compared to the wavelength of the waves that are launched. The possibility of exciting a shear wave with a plane front in the near zone is established, and an estimate of its intensity is made.
