N2 - A microstructural model of functional behavior of shape memory alloys has been used for modeling of the pseudo-elasticity effect taking into account the influence of latent heat of the martensitic transformations, heat exchange conditions and strain rate. A completely coupled boundary value problem on tension of a cylindrical rod under conditions of heat exchange with the environment and heat diffusion along the radius has been solved. The obtained results are in good agreement with the available experimental data. The Fourier and Biot criteria were used to evaluate the critical radius, for which it is necessary to solve a fully coupled boundary value problem at given material parameters, deformation rate and heat exchange conditions. It has been shown that the microstructural model taking into account the latent heat release and adsorption is an adequate tool for describing the strain rate dependence of the pseudo-elastic behavior for shape memory alloys.
