Simulation of ultrasonic arrays for industrial and civil engineering applications including validation

Abstract

In this contribution we address the beam field simulation of 2D ultrasonic arrays using the Generalized Point Source Synthesis technique. Aiming at the inspection of cylindrical components (e. g. pipes) the influence of concave and convex surface curvatures, respectively, has been evaluated for a commercial probe. We have compared these results with those obtained using a commercial simulation tool. In civil engineering, the ultrasonic inspection of highly attenuating concrete structures has been advanced by the development of dry contact point transducers, mainly applied in array arrangements. Our respective simulations for a widely used commercial probe are validated using experimental results acquired on concrete half-spheres with diameters from 200 mm up to 650 mm
