Taking account of the martensite inelasticity in the reverse phase transformation in shape memory alloys

The model of nonlinear deformation of shape memory alloys (SMA) is generalized to the case in which the possible structural transition in the reverse martensitic transformation is taken into account. The statement of active thermomechanical processes of proportional variation in the stress deviatoric components is justified. The problem of buckling on an SMA bar due to the reverse martensitic transformation is solved. It is shown that taking account of the structural transition under buckling in the process of reverse transformation significantly changes the solution of this problem.
