There has been much interest recently about the on-line structural health monitoring in plate-like structures using guided wave. The guided wave mode conversion phenomenon under through transmission scheme is simulated by the hybrid BEM and employed as a useful feature for defect location. The work presented here introduces a Reconstruction Algorithm for the Probabilistic Inspection of Damage (RAPID) which is used to construct tomographic images of defect. Through this study, we found a feasibility of defect image reconstruction based on the BEM modeling ad the tomograpy of guided waves.
