ABSTRACT
In recent years, guided waves have been successfully used for detecting defects in pipe and plate type structures such as concrete slabs and pipes, composite plates, metal plates and pipes, etc. This chapter gives the theoretical background for such inspection, lists advantages of the guided wave inspection technique over conventional ultrasonic techniques, and presents results from a number of plate and pipe inspection experiments. With this goal in mind, recent developments by the author and other investigators on plate and pipe inspection techniques that use guided waves are presented here.
