The Institute CEA LIST is one French public laboratory operated by the Technological research branch of the CEA (French Atomic and Alternatives Energy Commission). Its research is focused on digital systems with the vocation to bring technological innovation to industries. The Non Destructive Evaluation (NDE) activity at CEA LIST relies on the development of numerical tools and in particular the development of the collaborative CIVA simulation platform.  Since now many years simulation has proven to be a powerful tool for the design and demonstration of performance of ultrasonic inspections. The capability of models continuously and significantly evolve accompanying new needs from industry. Over the years, efforts are put on forwards models in order to increase the accuracy of the predictions in the most challenging situations. In parallel, new uses of simulation emerge. On one hand, the demand for intensive computations increase in particular for statistical studies aiming at a more comprehensive handling of uncertainties in the process of reliability assessment. On the other hand, new techniques emerge which, to be efficiently handled, require the development of model-based imaging or diagnostic tools, embedded in systems or processes. Technologies made available by data sciences offer the chance to complement physic-based models by data driven models. All these features are even amplified when we consider the emergence of Structural Health Monitoring (SHM). This presentation will give an overview of recent work carried out at CEA LIST in order to fulfill these different needs and applications.

Speaker Bios
Pierre Calmon received in 1990 his PhD in Physics at the University of Paris XI, France. Since then, he has been pursuing his research career in the field of Non Destructive Evaluation (NDE) at the French Alternative Energies and Atomic Energy Commission (CEA). He has been involved in the development of the CIVA simulation platform since its beginnings with a focus on ultrasonic modelling and ultrasonic array imaging. He is now scientific director of the NDE department of CEA, chairs the Scientific Hub of COFREND (the French NDT society) and is also vice-president of the NDT commission at the International Institute of Welding. His current fields of interest are reliability, simulation and data analysis for NDE and Structural Health Monitoring (SHM). 

Olivier Mesnil is a research engineer at the CEA. He is a former student of ENSTA Paristech and received a Ph.D. in aerospace engineering from Georgia Institute of Technology (Atlanta, USA) for the development of novel aerospace SHM techniques in 2016. His current research interests revolve around ultrasonic guided waves techniques for SHM with a focus on modelling and data processing for flaw detection and quantification as well as performance demonstration.
