PICASSO is a research collaborative project registered in the Seventh Framework Programme of the European Commission and coordinated by Snecma (Safran Group). The aim of PICASSO is to build a new and original concept of 'simulation supported Probability of Detection (POD) curves based on Non Destructive Testing (NDT) simulation in addition to existing experimental data base'. The POD method of analysis is generally used for quantitative NDT process capabilities assessment. NDT performances must be evaluated in order to ensure the desired level of safety and the POD curve provides a very useful method of quantifying the performance capability of an NDT technique. POD curves are thus used as a basis for: establishing design acceptance requirements and setting inspection maintenance intervals. Nowadays POD curves are obtained by expensive fully experimental campaigns and are even technically often impossible to realize. The objectives of PICASSO are: to have more accurate and reliable POD curves in order to get appropriate damage tolerance assessments for critical parts to address the potential risk of failure from induced anomalies (from material, manufacturing or service) within the Approved Life of the part, to overcome cost issue of the Probability of Detection campaign with Non Destructive Testing simulation techniques. This challenge is particularly important for metallic parts within the engine and aircraft industry. This paper presents PICASSO project : partners, objectives, overall strategy and progress.
