Impact localization in aircraft composite structures using GWO-VMD and adaptive correlation thresholding

Key Points

• Impact localization enhances structural integrity and safety in aircraft composite structures, improving overall performance.
• Using grey wolf optimization and variational mode decomposition shows a high localization accuracy of 90% in composites.
• Analysis with adaptive correlation thresholding enables better detection of damage compared to traditional methods.
• Improved methods may lead to more reliable assessments and proactive maintenance practices in aerospace engineering.
