Développement d'un modèle pour le contrôle non destructif par courants de Foucault de structures rivetées en aéronautique
Author: Séverine Paillard

ISBN:
Category :
Languages : en
Pages : 155
Book Description
One of the Eddy Current Testing issues in aeronautics is the inspection of fastened structures to detect flaws nearby rivets which can grow because of mechanical stress. EADS and the CEA LIST have started a collaborative work with the support of the Île-de-France Region to develop a simulation tool of EC fastened structures testing, integrated to the CIVA platform, aimed at conceiving testing methods, optimizing and qualifying it. The volume integral method using the Green dyadic formalism has been chosen in order to get a fast resolution of Maxwell equations. A first milestone was to build a simulation model of multilayer structures testing, thanks to the use of the multilayer Green dyads. Because of the rivet volume, 60 times bigger than the one of a typical flaw, a large number of discretization cells are needed. Therefore an iterative method has been developed in order to numerically solve large calculation zones. Finally, the flaw response simulation mostly has to cope with a scale issue between the size of the rivet and the one of the flaw, the latter being much smaller in a direction than the former. The whole model has been experimentally validated and compared to other simulation models (finite elements method, semi-analytical model and potential formulation) at the important development steps: multilayer configuration, iteration resolution, and flaw signature.

Improving the Effectiveness and Reliability of Non-Destructive Testing
Author: W.E. Gardner
Publisher: Elsevier
ISBN: 1483286983
Category : Technology & Engineering
Languages : en
Pages : 255
Book Description
This book is concerned with the two most important aspects of the use of non-destructive testing. Firstly, the effectiveness of procedures to detect and size the defects present irrespective of the geometry, materials involved or environment. Secondly, the reliability of instrumentation and personnel to perform the specified procedures. Validation and certification techniques required for the justification of safe operation of a plant are also discussed. Experts in industries where safety and defect detection are of paramount importance have made valuable contributions drawn from their experience to make this book essential reading for anyone responsible for safety of plant operation. Illustrated throughout, the book is also of interest to mechanical and structural engineers, researchers and inspectors as well as being a useful reference tool for graduate students.
