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 (500 kHz - 1 MHz). This mode is attractive for Non-destructive Evaluation (NDE) of bends in practical structures such as aerospace spar joints. Here the interaction of the SHB mode with transverse small-width notches (cracks) running across bends in plates is studied using 3D finite element simulations and validated by experiments. For through-thickness cracks, the influence of transverse crack length on SHB mode reflection is studied. For part-depth but long cracks (transverse length greater than operating wavelength), influence of crack depth on mode reflection is studied. The results demonstrate the potential of the SHB mode for NDE of bent plate structures. © 2015 The Authors.
