概要
A previously introduced two-dimensional EMAT (Electro-Magnetic Acoustic Transducer) simulation code developed in-house at JAEA, based on both coupling/uncoupling of eddy currents and wave displacement in a non-magnetic material is analyzed against 3D numerical simulations and experimental wave displacements performed by JAPEIC. The experimental setup visualizes wave propagations along the vertical surface of a stainless steel plate using a piezoelectric sensor, while the 3D simulations were performed using an un-coupled model of EMAT based on two commercial codes: EMSolution for the eddy currents and COMWAVE for the wave propagation.
