The anisotropic and nonlinear behavior of doubly oriented and non-oriented sheets are modeled using the coenergy density. These models have been implemented in a finite element computation. A large generator has been modeled and the advantages of doubly oriented sheets compared to the conventional non-oriented ones are shown.

In this paper a two dimensional and anisotropic magnetization model based on magnetic considerations has been proposed. In the range of irreversible 180 [degree] domain walls' displacements, the interactions between the different classes of the magnetic domains have been taken into account through first a simple energetic minimization with respect to the volumic fraction of one of these two classes, and then by the magnetization curves in the longitudinal and the transverse directions. The magnetic momentum rotations have been introduced afterwards in an energetic equilibrium calculation. The 'doubly oriented' and 'grain oriented' magnetic sheets have been considered and the model has provided rather interesting results.
