摘要：

A new method for modelling stress-strain characteristics of demagnetized polycrystalline ferromagnets is presented, taking into account changes in the magnetic domain structure due to the application of stress. The materials are assumed to be isotropic polycrystalline aggregates with crystallites of cubic symmetry. Introducing a mesoscopic variable, the change of magnetic domain volumes, the analytical form of nonlinear stress-strain behaviour is derived. Together with a quantitative description of the well known DELTAE effect in uniaxial stress state, a DELTAG effect is predicted, which is a decrease in shear modulus G taking place in shear deformations.
