Crack Localization Using Improved Continuous Wavelet Transform Features

  • 88 Accesses

Part of the Lecture Notes in Mechanical Engineering book series (LNME)

Abstract

In this paper, an enhanced damage diagnostic strategy for the localization of subtle cracks is proposed using modal parameters. The proposed work applies continuous wavelet transform (CWT) on the traditionally followed mode shape difference between the structure with and without crack as crack localization index (CLI). The CLI is further enhanced by augmentation of weighting function involving natural frequencies. This weighting function emphasizes the modes that are sensitive to crack, which improves the crack diagnosis process. Numerical studies and lab-level experiments have been performed on structures with varied crack parameters to validate the improved CWT-based proposed approach.
