Abstract
Disclosed is a magnetostrictive transducer for generating and receiving elastic waves in a testing plate and an apparatus for structural diagnosis using the magnetostrictive transducers. More particularly, disclosed is a magnetostrictive transducer which may generate and transmit elastic waves using the magnetostrictive effect in any directions without re-attaching ferromagnetic patch on the non-magnetic testing plate and may produce Lamb waves and Shear Horizontal (SH) waves in desired directions, and an apparatus for structural diagnosis using the magnetostrictive transducers. There is provided a magnetostrictive transducer comprising: a patch made of ferromagnetic material; and a magnetic field generator for generating magnetic field applied to the patch, the magnetic field generator being placed on the patch, wherein the magnetic field generator comprises: a main body; two magnets for generating bias magnetic field, the magnets being apart from each other; and a coil for winding around the magnets.
