International audience; Structural damages can result in nonlinear dynamical signatures that can significantly enhance their detection. An original nonlinear damage detection approach is proposed that is based on a cascade of Hammerstein models repre

International audience; A fundamental problem in structural damage detection is to define an efficient feature to calculate a damage index. Furthermore, due to perturbations from various sources, we also need to define a rigorous threshold whose over

Proper orthogonal decomposition applied to structural health monitoring

Autor: Michel Vergé, Nazih Mechbal, Rafik Hajrya

Publikováno v: 2011 International Conference on Communications, Computing and Control Applications (CCCA).

This paper describes the application of proper orthogonal decomposition (POD) method in the context of structural health monitoring of a smart structure, bonded with a distributed piezoceramic patches array. Using measurements given by the distribute

Active damage detection and localization applied to a composite structure using piezoceramic patches

Autor: Nazih Mechbal, Michel Vergé, Rafik Hajrya

Publikováno v: 2010 Conference on Control and Fault-Tolerant Systems (SysTol).

This paper describes the application of an active structural health monitoring technique for a composite plate bonded with a distributed piezoceramic patches array. To maximize the performance of a structural health monitoring (SHM) system, an optima
