%X The conception of shape memory factor is defined to describe the superelasticity and shape memory effect of shape memory alloys. From the differential relationship between martensite fraction and free energy during phase transformation, a shape memory factor evolvement equation is established. Based on micromechanics theory, a 3-dimension constitutive model with considering the process of martensitic reorientation is developed, which possesses simpler mathematics form and clearer physics meaning than the previous models with the same functions.
