Non-destructive Testing and Evaluation (NdT-NdE), the Whys and the Hows, and Some Illustrations

Dominique Lesselier

内容简介:

Main questions open
-- How to ensure the integrity of industrial infrastructures in transportation, civil engineering, energy production and distribution during entire lifetime?
-- A host of data is needed to take exploitation decisions and to manage risk
Conditions of operation evolve
-- Increase of performance from new technologies, operating modes, system optimizations
-- Environment/regulatory changes
-- Lifetime management & maintenance strategies
Present-day limits still around
-- Costs of interrupted production due to manual controls
-- Use of specific machines expensive and custom-built
-- Numerical simulation studies not fully mature to provide optimization guidelines
-- Few robots in service tailored to Ndt-NdE
One needs to develop both
-- Instruments and tools
-- Computational modeling and imaging methods
Two examples* of electromagnetic NdT-NdE
-- Microwave inspection of disorganized fiber-based composite laminates
-- Eddy-current NdT of metallic parts via Bayesian inversion
 
报告人简介:Dominique Lesselier is with the Centre National de la Recherche Scientifique (CNRS) as Researcher since October 1981 and Research Director since October 1988. He is currently with the Laboratoire des Signaux et Systèmes, UMR8506 (CNRS, CentraleSupélec, Université Paris-Sud), Université Paris-Saclay, Gif-sur-Yvette, France.  As Director (2006-2009) of the Groupement de Recherche CNRS GDR Ondes,he managed a broad network of scientists involved in the science of waves. His research interests include development of solution methods of inverse and imaging problems, from mathematics to numerics to applications, and vice versa.
