Description

The detection of surface breaking cracks at the opposite side of a plate is of practical interest when the opposite side of the plate is inaccessible. Ultrasonic techniques using a single PZT transducer have been used to detect and characterize opposite side surface breaking cracks [1]. By considering the effects of curved surfaces, the technique using a single transducer has been employed to inspect pipes and boiling water reactors for cracks located on their inner walls [2].
