Caloric Effects Induced by Uniform and Non-uniform Stress in Shape-Memory Materials

Abstract A Ginzburg–Landau model is developed that adequate to describe a square-to-rectangle martensitic transition with associated shape-memory and superelastic properties. Using this we study caloric effects in the vicinity of induced by stress compare case uniform uniaxial non-uniform continuous distribution stresses produce bending material. The former corresponds an elastocaloric effect latter flexocaloric effect. aim work quantitatively both cases, which show must be accomplished terms equal amounts exchanged mechanical work. It then obtained more efficient for low but less large
