Abstract

Based on thermodynamics and phase transformation driving force, a SMA constitutive model is provided. Simulations under different loading illustrate the influence of large strain deformation and small strain deformation on the characteristics of the model. The results indicate that the difference between the two methods is small under uniaxial tension, while the influence is very different under shear deformation case. The result has been stimulated by a example which test efficiently the result.
