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 distributed sensors, we propose a damage index (DI) based on change in angle between subspaces. Furthermore, from statistics, we propose a threshold that automatically...
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 optimal placement of these patches has been proposed using grammians of controllability and observability and the H∞ modal norm. The proposed approach was established...
