The Perzyna type of material models, which is based on socalled overstress, has been used. The constitutive law, known as Lemaitre's creep model is based on the use of internal state variables attached to specific phenomena, including hardening of material. The identification of model was carried out with aid of genetic algorithms and experimentally obtained data.  The used genetic algorithm is based on differential evolution scheme and was adapted for fast model parameter identification.
