The method for calculation of cylindrical sample rheological deformation and fracture in creep conditions for three types of stress state: tension, pure torsion, the combined effect of tensile load and torque is offered. The procedure is based on the theory of creep and creep rupture strength of energy type. Calculations are performed for all three types of stress state for solid and hollow cylinder tests from aluminum alloy D16T at $250\,^\circ\mathrm C$. Comparison of the calculated data with the corresponding test data for each type of stress state is conducted. It shows the agreement between the calculated and experimental values. The intensification of creep and decreasing of creep rupture strength factors after the application of torque to the specimen under the axial tension are established. The substantial redistribution of axial and shear stresses along the radius depending on the time is observed. The estimates of errors of deviation of calculated data from the experimental values are given.
Keywords: creep, creep rupture strength, cylindrical sample, tension with torsion, the method of calculation, test data, alloy D16T.
