- 01HS12GJR6H4D3T6FHP9TR039E abstract "Composite structures consist of two, or more, different material types, with the aim to exploit the beneficial properties of all. Due to the advantages of optimized performance, weight reduction, improved corrosion resistance, and high design flexibility, composite structures are increasingly used in the areas of renewables, aerospace, automotive and civil infrastructures. However, A challenge associated with the utilization of composite pertains to the potential presence of internal damages or defects. To ensure the secure functioning of composite components, it is imperative to conduct inspections for internal defects both post-production and at regular intervals throughout their operational lifespan. Recently, damage detection using guided elastic waves and nonclassical nonlinearity demonstrates promising potential. A non-destructive testing procedure is suggested for detecting damage in composites by employing full wavefield measurements utilizing a scanning laser Doppler vibrometer. Vibrations are excited using two piezoelectric actuators, resulting in nonlinear elastic wave modulation at the location of the defect. Initially, a time–frequency filtering approach is introduced to extract specific nonlinear components of interest. Subsequently, damage maps are constructed through a bandpower calculation of these filtered nonlinear components. It is illustrated that the modulation sidebands offer a distinct imaging of defect nonlinearity, unaffected by potential source nonlinearity. This proposed method for constructing damage maps is applied to various test specimens including glass fiber reinforced polymer and sandwich panels.".
