| Summary: | The paper describes the experimental results obtained for the combined loading of the specimens in the region of high-cycle fatigue. The specimens were manufactured from common structural steel 11523.1, melt T31052. The following experiments were performed: The first set of the specimens was loaded by the alternating torque amplitude. The second set was loaded by the in fully reversed push-pull. The third set of specimens was loaded by the combination of the torque and of the fully reversed push-pull. The phase shift is zero in this experiment. The results were evaluated by the modified conjugated strength criterion and other generally used multiaxial fatigue criteria. The stress-strain analysis of the specimens by FEM was performed to determine parameters (constants) of particular strength criteria. |
