Results of 2006 UT Modeling Benchmark Obtained with CIVA at CEA: Beam Modeling and Flaw Signal Prediction

摘要

This benchmark is to compare experimental data with results of simulation. The experimental setup involves pulse-echo responses on planar backwall breaking defects using P- or SV-wave contact transducer. The interest is to evaluate the influence of a varying slope of the backwall on the corner trap detection. CIVA software developed for processing and simulating NDT data is used. Comparisons between experiments and simulations of echo-graphic responses of rectangular defects at different variations of the backwall slope of the block are presented.
