Abstract
In the current work, an algorithm based on wavelet transformations is used to detect damage prior to the degradation of structural parameters of plates. Plates are of interest because they are basic building blocks for many structures, such as naval ships. Damage to the connecting joints and in the form of through thickness cracks, along with material and temperature variations are included in the analysis. Dynamic loading conditions consisting of impulse and chaotic oscillations are examined. The wavelet algorithm is applied to sensor data in the form of time histories (e.g. strain). These histories are either measured experimentally or generated via finite element analysis. Sensitivity, robustness, and potential uses of this wavelet algorithm for damage detection are discussed.
