“…Magnetostriction is technically exploited in actuation systems, and there is a variety of applications for permanent magnetic fields of poled ferromagnetic devices. New concepts combine ferromagnetic and ferroelectric phases in the so-called multiferroic composites (Bibes and Barth el emy, 2008;Buchanan, 2004;Eerenstein et al, 2007;Fiebig, 2005;Hill, 2000;Lu et al, 2011;Nan, 1994;Nan et al, 2008;Scott, 2007) in order to induce a coupling of electric and magnetic fields. All these applications require the knowledge of the constitutive behaviour of the employed ferromagnetic material.…”

A constitutive modelling of ferromagnetic materials under combined magnetomechanical multiaxial loading with different boundary conditions and a finite element implementation are presented. The phenomenologically motivated model is capable of predicting magnetisation, strain, and stress and is thus suitable, e.g., for applications in multiferroic composites. The approach covers a reversible nonlinear behaviour as it is observed, e.g., in cobalt ferrite and other soft magnetic alloys. Various examples demonstrate the suitability of the model and its numerical implementation and give an insight into the behaviour of soft magnets, exposed to different boundary conditions or being embedded into other compliant materials.

“…The phase field approach, for the past 15 years having experienced a continuous increase in popularity in various fields of application, has also been exploited toward modeling ferromagnetic materials (Entel et al, 2006;Koyama, 2008;Koyama and Onodera, 2003;Lu et al, 2009Lu et al, , 2011Ma et al, 2014;Miehe and Ethiraj, 2012;Zayak et al, 2002). Based on an energy functional and the Ginzburg-Landau equation, corresponding to subcritical bifurcation and being derived from a Landau-Lifshitz-Gilbert equation of motion of the magnetization in a one-dimensional uniaxial ferromagnet, the domain wall motion is calculated in terms of an evolution of phase fields.…”

The coupling of magnetic and mechanical fields due to the constitutive behavior of a material is commonly denoted as magnetostrictive effect. The latter is only observed with large coupling coefficients in ferromagnetic materials, where coupling is caused by the rotation of the domains as a result of magnetic (Joule effect) or mechanical (Villari effect) loads. However, only a few elements (e.g. Fe, Ni, Co, and Mn) and their compositions exhibit such a behavior. In this article, the constitutive modeling of nonlinear ferromagnetic behavior under combined magnetomechanical loading as well as the finite element implementation is presented. Both physically and phenomenologically motivated constitutive models have been developed for the numerical calculation of principally different nonlinear magnetostrictive behaviors. On this basis, magnetization, strain, and stress are predicted, and the resulting effects are analyzed. The phenomenological approach covers reversible nonlinear behavior as it is observed, for example, in cobalt ferrite. Numerical simulations based on the physically motivated model focus on the calculation of hysteresis loops and the prediction of local domain orientations and residual stress going along with the magnetization process. Finally, a model for ferroelectric materials is applied in connection with the physically based ferromagnetic approach, in order to predict magnetoelectric coupling coefficients in multifunctional composite.

“…However for composite magnetoelectric medium due to the coupling of the magnetic and mechanical fields at the piezomagnetic phase m m and the coupling of the electric and mechanical fields at the piezoelectric phase e e as the result we get the coupling of magnetic and electric fields that does not exist at each separate phase. Recently magnetoelectric composites became of interest to many researchers so the number of works devoted to the modeling of the effective properties of these composites has increased considerably (see [1,[3][4][5][6][7], etc. ).…”
