This paper presents a new acoustic emission (AE) source localization forisotropic plates with reflecting boundaries. This approach that has no blindspot leverages multimodal edge reflections to identify AE sources with only asingle sensor. The implementation of the proposed approach involves three mainsteps. First, the continuous wavelet transform (CWT) and the dispersion curvesof the fundamental Lamb wave modes are utilized to estimate the distancebetween an AE source and a sensor. This step uses a modal acoustic emissionapproach. Then, an analytical model is proposed that uses the estimateddistances to simulate the edge-reflected waves. Finally, the correlationbetween the experimental and the simulated waveforms is used to estimate thelocation of AE sources. Hsu-Nielson pencil lead break (PLB) tests wereperformed on an aluminum plate to validate this algorithm and promising resultswere achieved. Based on these results, the paper reports the statistics of thelocalization errors.
