Shear horizontal wave transduction in plates by magnetostrictive gratings

Quantification and imaging of corrosion wall thinning using shear horizontal guided waves generated by magnetostrictive sensors

“…The use of magnetostrictive (MS) patch transducer is an efficient approach to generate and measure SH waves [22]. The crosssectional diagram of MS transducer module is shown in Fig.…”

Enhanced transduction of MPT for antisymmetric Lamb waves using a detuned resonator

“…It is common practice to increase the output power of most transducers, including MPTs, using the internal resonance or wavelength matching. In the case of MPTs, the size of the magnetostrictive patch that is coupled with a test specimen should match the wavelength of the wave excited in a test specimen at the excitation frequency [6,13,14]. As MPTs operate on the magnetostrictive principle, one may also consider optimizing the magnetic circuit to increase the transducer output [5,15].…”

Semi-analytic formulation and its experimental verification to determine the radiation patterns of ultrasonic guided waves generated on a plate by a magnetostrictive patch transducer

“…In many cases, this phenomenon is named the "Joule effect" after its founder, Joule [7]. Magnetostrictive material has been developed recently in the form of patch transducers, that is, Magnetostrictive patch transducers (MPT), and has been extensively studied as a tool for structural health monitoring, as with plates and shells [8][9][10][11][12][13][14][15][16][17][18][19][20]. A previous review [8] summarized the up-to-date accomplishments in the area of MPT coverage not only in plate structures but also in pipe and rod structures.…”
