Abstract
The subject of this paper is the modelling of magnetoelastic effects in isotropic ferromagnetic materials. In these materials, the processes are hysteretic and therefore inherently irreversible in nature. A coherent description must take into account the description of irreversibility. A phenomenological analysis of magnetoelastic couplings is presented. The framework of non-equilibrium thermodynamics theory is used. This allows a classification of magnetoelastic interactions in two categories, those appearing in the free energy expression, and those appearing in the intrinsic dissipation of the system. Various couplings are be illustrated by the choice of the potential function and the intrinsic dissipation. The material properties are supposed to be rate independent and homogeneous.
