Abstract:
1. A flexible plate-type magnetostrictive sensor (MsS) probe for inspection of structures having surfaces that may vary from planar to cylindrical in curvature, the MsS probe comprising: (a) a flat flexible cable (FFC) coil assembly, the FFC coil assembly having a top face and a bottom face, the FFC coil assembly comprising: (b) a flexible strip of magnetostrictive material, the flexible magnetostrictive strip adhered to the bottom face of the FFC coil assembly; wherein time varying current in the FFC coil assembly causes guided-waves to be generated in the magnetostrictive strip, which guided-waves, when the magnetostrictive strip is positioned against the surfaces of the structure, travel to and are reflected by anomalies in the structure under inspection.
