ABSTRACT
The class of models presented here, targeting the modelling of hysteresis
processes in the magnetic and elastic properties of ferromagnetic composites,
is based on the Preisach formalism. The 1D and 2D formulations are equipped
with a set of five different local hysteresis operators, to address different
hysteretic responses. The resulting algorithms are efficient enough to be used
as core models in simulations or real-time control. The types of hysteretic
responses discussed and modeled include the magnetization vs. magnetic field
response, M(H), the deformation vs. temperature response, x(T), and the
deformation vs. field response, l(H), also known as magnetostriction.
