Description

In recent years, attention has shifted from the ultrasonic NDE of bulk flaws to flaws in structural components that involve nearby surfaces. Very often it is convenient to exajnine the part in a water tank, locating the transmitting/receiving transducers in water. This paper is concerned with a theoretical study of a near surface flaw in an immersion tank experiment. The analytical problem to be studied is the scattering of ultrasound by an obstacle that is located near a solid-fluid (water) interface. The distance ‘d’ of the center of the flaw from the interface ranges from ‘a’ to ‘15a’ where ‘a’ is a typical radius of the flaw.

Wave Scattering by Obstacles in Joined Fluid-Solid Half Spaces

In recent years, attention has shifted from the ultrasonic NDE of bulk flaws to flaws in structural components that involve nearby surfaces.
