Abstract

Ultrasonic testing of a thick plate with a rectangular crack in a cladding is modelled analytically for a fully three-dimensional case. The effects of a corrugated interface and anisotropy are both taken into account. The wave scattering problem is solved by a hypersingular integral equation approach. A model for the ultrasonic transmitter and receiver is also included. Some preliminary numerical results for the change in signal response due to the presence of the crack are given.
