According to relation of texture - magneto-crystalline anisotropy energy of cold rolled non-oriented silicon steel
the C coefficient of orientation distribution function and M coefficient of magneto-crystalline energy distribution function MDF are obtained by calculation of texture orientation distribution function ODF program to calculate magneto-crystalline anisotropy eneiy of non-oriented silicon steel (0. 004C
0. 33Si) at each macro direction. The simulation results show that the textures of polycrystalline materials influence magneto-crystalline anisotropy energy
