Description

The development of analytical computer models to predict ultrasonic scattering from individual, small flaws in components with complex geometries [1,2] has undergone considerable work. These models, known as the ultrasonic measurement model, are based on the Gauss-Hermite beam model [2] and account for the effects of diffraction and refraction of the ultrasonic beam, mode conversion at the water-solid interface and material attenuation. Potential uses include increasing confidence in obtaining a reasonable probability of detection of a critical flaw, assisting in developing a scan plan for a particular geometry and combination with a computer aided design package as an additional design aid.
