ABSTRACT
This communication presents the results obtained on the configurations proposed in the 2009 UT modelling benchmark with the ultrasonic models implemented in the CIVA software platform. The aim, this year, is to study the relative amplitudes and the shapes of specular and corner echoes for different flaws in “2D” and “3D” configurations. Experiments have been performed with contact probes (single element or phased array) radiating transversal or longitudinal waves at 45° incidence angle on planar mock-ups containing flat-bottom hole, side-drilled holes and backwall breaking notches of different heights and widths. The echoes are simulated by applying an integral formulation for the field radiated by the probe (the pencil-model) and different scattering models depending on the kind of defects. Comparison between simulated and experimental results are presented and discussed.
