Anisotropic Vector Hysteresis Modeling Under Multiaxial Stress

A model for predicting the vector hysteresis properties of non-oriented steel sheets under multiaxial stress is proposed. In this model, the sensibility of mechanical stress is accounted for both in the reversible and irreversible magnetization based on the magneto-elastic energy of single crystal and domain motion theory. Comparisons between measured and calculated curves and losses are performed to validate the model.
