Abstract. In Part I of the paper we use a simplified 1D thermomechanical model to describe the behavior of SMAs. We prove that this model can describe the existence of the hysteresis loop and the pseudoelastic behavior of SMAs. In Part II of the paper we show that the same model predicts the stress relaxation and the strain creep during martensitic transformation. We present experimental results concerning stress relaxation and strain creep. The theoretically calculated and the experimentally deduced stress relaxation and strain creep curves are in satisfactory agreement.
