Abstract

This chapter explores the innovative combination of modal strain energy (MSE) and convolutional neural networks (CNN) for damage identification in plate-like structures. The study introduces a one-step process that leverages the sensitivity of MSE to structural damage and the robustness of CNN algorithms. Through finite element analysis, the MSE of an aluminum plate is determined, with damage severity measured as a percentage of thickness reduction. The proposed CNN architecture, featuring 2D convolutional layers and dense layers, is trained on a dataset of random damage scenarios. The results demonstrate the method's high accuracy in identifying single and multiple damages, with identification capacity indicators exceeding 80%. The study also investigates the effectiveness of combining MSE data from six bending mode shapes, further enhancing prediction performance. This research highlights the potential of integrating deep learning with traditional structural health monitoring techniques, offering a promising approach for efficient and accurate damage identification in plate-like structures.
