A constitutive equation for shape memory alloys, which governs the thermomechanical as well as the transformation processes of the materials, was presented in the process of stress-induced martensitic transformation. A theoretical chain connecting the deformation of microstructures and the macroscopic behavior of alloys was well established by introducing two different microstructural levels of alloys; the microregion and the mesodomain. All material parameters in the constitutive equation are shown to be fully determined from the microscopic material data.
