Nondestructive Damage Assessment of Composite Structures Based on Wavelet Analysis of Modal Curvatures: State-of-the-Art Review and Description of Wavelet-Based Damage Assessment Benchmark

摘要: The application of composite structures as elements machines and vehicles working under various operational conditions causes degradation occurrence damage. Considering that composites are often used for responsible elements, example, parts aircrafts other vehicles, it is extremely important to maintain them properly detect, localize, identify the damage occurring during their operation in possible early stage its development. From a great variety nondestructive testing methods developed date, vibration-based seem be ones least expensive simultaneously effective with appropriate processing measurement data. Over last decades popularity structural has been gained by wavelet analysis due high sensitivity This paper presents an overview results numerous researchers area assessment supported detailed description Wavelet-based Structural Damage Assessment (WavStructDamAs) Benchmark, which summarizes author’s 5-year research this area. benchmark covers example problems identification types using transforms supporting tools. openly available allows performing on well own
