An algorithm is implemented to simulate a pure bending of a beam of a symmetric section under creep conditions. The beam is subjected to a bending moment with a constant absolute value. The algorithm is applied to the experimental data on the pure bending of T-beams made from a Ti-Al-Sn-V alloy at a temperature T = 700°C. The algorithm takes into account the accumulation of damage in the material, the effect of temperature exposure and the difference properties of the material under tension and compression. The model is based on kinetic creep theory by Rabotnov. The Nelder-Mead procedure is used to find the bending moment by the curvature of a beam.
