An electromagnetic acoustic transducer (EMAT) induces without contact dynamic sources in a ferromagnetic material which radiate ultrasonic waves used for its nondestructive evaluation (NDE).Taking account of the anhysteretic magnetic and magnetostrictive constitutive laws predicted by a simplified multiscale approach, the transduction model derives the electro-magnetic and magnetostrictive stresses tensors, well-fitted for the definition of electromagnetic and magnetostrictive sources induced by EMAT, irrespective of the piece geometry, of the material properties and of the transducer design.To efficiently predict ultrasonic field radiation with the CIVA platform, a method to transform body sources into equivalent surface stresses is develo...
