The fundamental shear horizontal (SH0) wave in plate-like structures is extremely useful for non-destructive testing (NDT) and structural health monitoring (SHM) as it is non-dispersive.However,currently the SH0 wave is usually excited by electromagnetic acoustic transducers (EMAT) whose energy conversion efficiency is fairly low.The face-shear (d36) mode piezoelectrics is more promising for SH0 wave excitation but this modecan only exist in single crystals of specific point groups and cut directions.Theoretically the d36 coefficient vanishes in piezoelectric ceramics because of its transversally isotropic symmetry.In this work,we modified the symmetry of poled PZT ceramics from transversally isotropic to orthogonal through ferroelastic domain switching by applying a high lateral stress along the “2” direction under elevated temperature (80℃ for PZT-5H and 110℃ for PZT-4) and holding the stress for several hours.After removing the compression,the piezoelectric coefficient d31 is found significantly larger than d32.Then by cutting the compressed sample along the 45°direction,we realized d36coefficients up to 270 pC/N in PZT-5H ceramics and 108 pC/N in PZT-4 ceramics.We then successfully excite SH0 wave in the aluminum plate using a face-shear PZT-4 square patch and receive the wave using a face-shear PMN-PT patch.The frequency response and directionality of the excited SH0 wave were also investigated.The SH0 wave can be dominate over the Lamb waves (SO and A0) from 160 kHz to 280 kHz.The wave amplitude reaches its maxima along the 0°and 90°directions,symmetric along the 45°direction.The amplitude can keep over 80% of the maxima when the deviate angle is less than 30°,while it vanishes quickly at the 45°direction.The excited SH0 wave using piezoelectric ceramics could be very promising in the fields of NDT and SHM.Finally,excitation and reception of SH waves using another face-shear (d24) mode piezoelectric wafers were also investigated.
