Surveillance de la santé structurelle poncée utilisant des approches de traitement du signal émergentes avec des informations artificielles

     Structural health monitoring is a powerful tool across civil mechanical automotive and aerospace engineering allowing the assessment and measurement of physical parameters in real time Processing changes in the vibration signals of a dynamic system can detect locate and quantify any damage existing in the system This book presents a comprehensive state of the art review of the applications in time frequency and time frequency domains of signal processing techniques for damage perception localization and quantification in various structural systems r n r nExperimental investigations are illustrated including the development of a set of damage indices based on the signal features extracted through various signal processing techniques to evaluate sensitivity in damage identification Chapters summarize the application of the Hilbert Huang transform based on three decomposition methods such as empirical mode decomposition ensemble empirical mode decomposition and complete ensemble empirical mode decomposition with adaptive *ise Also the chapters assess the performance and sensitivity of different approaches including multiple signal classification and empirical wavelet transform techniques in damage detection and quantification Artificial neural networks for automated damage identification are introduced r n r nThis book suits students engineers and researchers who are investigating structural health monitoring signal processing and damage identification of structures
