Analysis of a Multiple-Operators Database for MAPOD Study of Ultrasonic Pulse-Echo Response from Side-Drilled Holes

The development of NDT simulation tools allows developing Model Assisted Probability Of Detection. MAPOD requires experimental data to validate modelling choices. We provide in this study multiple-operators data related to the inspection of steel components using contact ultrasound probe. We obtain noise distribution and side-drilled hole responses for two frequencies. The analysis of the variations of the results due to the origin of the operator is presented. We compare results with appropriated statistical laws. First simulations using CIVA code allow introducing the discussion towards the Design of Numerical Experiments. With these data POD points could be obtained. This work is a part of the SISTAE project (Simulation and Statistics for NDE) supported by the French National Research Agency (ANR).
