A study of magnetic particles' behavior by magneto-Cosserat continuum theory

By implementing the magneto-Cosserat continuum theory in FEM scheme, it is possible to simulate magnetic alignment in powders with magnetic anisotropy during compaction in an applied magnetic held, We thereby analyze the rela tionship between the direction of magnetic field and compaction process, su ch as cross compaction and parallel compaction. The rotation of the axes is thus calculated at various conditions of applied magnetic field, In our pr evious study, Cosserat constant beta was given arbitrarily The method to ca lculate the Cosserat constant beta is proposed and its effect on the rotati on of the particles' easy axes is discussed. As a demonstration of the deve loped method, magnetic particles' alignment during compaction in an applied magnetic held is simulated. The calculated results are in good agreement w ith the experimental ones.
