This work focuses on damage localization of composite materials using Lamb wave. The work extends the widely known ellipse method. It combines the ellipse method and the probabilistic inspection of defects (RAPID) method to achieve an accurate damage identification. The Bayesian method is used to fuse the two algorithms, and estimate the damage location from the posterior distribution. Finite element simulation is used to demonstrate the performance of the proposed method. The delamination is simulated within three sets of quasi-isotropy composite plates. Numerical results obtained with different damage locations in composite plates validated the performance of the proposed algorithm. Results highlighted the accuracy and robustness of the new algorithm.
