Scattering of a normally incident longitudinal wave by a disk-shaped cavity in an elastic body
Abstract
The paper is concerned with the problem of the scattering of an elastic monochromatic wave propagating in an infinite isotropic elastic body and encountering an obstacle in the form of an infinitely long thin disk-shaped crack. The problem is solved by using the variable-separation (Fourier) method. The solution provides a way to calculate fields scattered by common types of plane defects in ultrasonic fault detection.
