Abstract: The magnetic and the mechanical constitutive equations are proposed
on the basis of the continuum theory of magnetoelastic materials. The rate type
expression is derived from the moving Preisach model by taking into account the
stress dependence as the magnetic constitutive equation. From the symmetry of
the constitutive equations, it is shown that the stress magnetization effect
can be derived from the stress-dependent magnetization and magnetostriction
curves. It is experimentally confirmed that the constitutive equations can
describe typical magnetoelastic behaviors of a ferromagnetic material such as
the magnetization and the magnetostriction curves under the stress and the
stress magnetization curve.
