Implementation of the Magnetic Anisotropy in 2D Finite Element Method Using the Theory of Orientation Distribution Functions

Abstract

In this work the magnetic anisotropy phenomenon in ferromagnetic materials was modeled using Orientation Distribution Function (ODF). The ODF is a concept that can be used to model the first magnetization curve of electrical steel sheet along any magnetization direction. The model is inserted in a 2D Finite Element (FE) field calculation software with vector magnetic potential formulation. Aspects related to the inclusion of the model in the formulation and its performance are discussed.
