Summary:
The discovery and identification of damages in engineering structures is very important in the field of engineering maintenance, as it is a great
challenge in presenting new methods in measuring vibrations and discovering damages with the development in the field of automation and
high accuracy in discovering damages. In this study, natural frequencies and mode shapes of transverse vibration for damage detection in
structures are investigated. The study is performed for various crack depth and crack location. And suggested a new technique based on
Continuous Wavelet Transform (CWT) and Convolution Neural Network (CNN). The comparison will be done by simulating the oscillations
of a cantilever steel beam with and without defect as a numerical case. The proposed new technique proved to outperform classical methods
and has achieved a100% accuracy in the identification of defect position for the data studied.
