Structural Health Monitoring An Integrated Approach

Structural health monitoring (SHM) is a multidisciplinary problem that involves modeling and simulation, damage detection, information management and prognosis. This book is designed to provide readers with a clear idea of all the challenges that need to be tackled before an SHM system can be implemented in real structures. It emphasizes the multidisciplinary nature of this topic and covers the key elements and approaches used to model and monitor structures for damage state assessment and estimation of remaining useful life.
