This paper uses the socalled modulated perturbation method by combining the Rayleigh-Schrӧdinger perturbation theory with the Levi-Civita transformation and including a variational parameter. The advantage of the constructed method is demonstrated in calculating the exciton diamagnetic coefficient within the second order of approximation. The results are then compared with recent experimental ones.

This paper aims to develop a novel constitutive model dependent strain rate with free energy which is based on the model of damage and dissipation “plasticity-like”. Moreover, the effect of strain rate will be taken into account in critical driving force. The model can describe the superelastic behavior of SMA considering the effect of strain rate.
