Abstract :
Aiming at a reduction in time and high efficiency in computation, a set of simple formulas characterizing a giant magnetostrictive material is proposed. It can represent nonlinearity of the magnetic properties with respect to both the magnetic field intensity and the mechanical stress, using easy-to-handle formulas with some adjustable parameters read from measured data resources.
