Description

Ultrasonic transmission through a moderately curved fluid-solid interface is a problem of obvious practical interest to QNDE. Extreme surface curvatures result in an erratic transmitted beam geometry ill-suited for a measurement probe. However, in many (if not the majority) of cases, a component surface has a moderate machined or cast curvature which distorts the beam in a well-behaved manner, making the prospect of an ultrasonic inspection viable. The quantitative utility of such an inspection will depend on the ability to model this beam distortion.
