A Computational Effective Material Data Representation for Fast Simulation Models of Giant Magnetostrictive Materials

摘要

Aiming at time reduction and high efficiency in computation, a set of simple formulae characterizing a giant magnetostrictive material is proposed. It can represent non-linearity of the magnetic properties with respect to both the magnetic field intensity and the mechanical stress, using easy-to-handle function form with some adjustable parameters given by from experimental data resources.
