The solution of boundary problems for shape memory alloy cylinder and plate


A connected thermomechanical boundary problems for TiNi cylinder and plate, loaded by an external force and subjected to cooling or heating from the surface, has been solved. The constitutive relations are given by the microstructural model. Even for a low cooling rate, the temperature, stress, and martensite volume fraction are inhomogeneous, and the transformation-induced strain in the force direction decreases with an increase in the temperature rate.
