Damage Detection Of Mixed-Mode Cracks In Large Truss Structures Using Wavelet Transform, Hussain Altammar

Theses and Dissertations

The use of dynamic response in damage identification has been gaining considerable attention over the last two decades. The aim of these methods is to detect the presence of a defect or a crack in components or structures. This study focuses on using modal properties for the damage detection of mixed-mode cracks in truss structures. The behavior of a mixed-mode crack is simulated by developing a macroscopic model that is integrated with the finite element model of a truss structure. The modal properties obtained from the model of the damaged structure are found to be comparable to the results of …
