A phenomenological model for the non-linear magnetomechanical coupling in ferromagnetic materials

摘要

In this paper, both experimental and theoretical results on non-linear constitutive modeling of ferromagnets are presented. It is analogy to elastic-plastic crystal plasticity theory in which magnetic domain wall motion is treated in the same manner as slip in elastic-plastic crystals. The remanent magnetization and strain are considered as internal variables. The one-dimensional model is developed and compared with experimental results.
