Recent research by the authors has revealed the presence of shear horizontal-type of feature-guided (SHB) waves in plates with 90˚ transverse bends. The SHB mode is non-dispersive and has low attenuation over a range of higher frequencies (500kHz – 1MHz). This mode is attractive for Non-destructive Evaluation (NDE) of bends in practical structures such as aerospace spar joints. Here the interaction...
