Experiment in Multiaxial Fatigue, Combined Loading,High-Cycle Fatigue, Multiaxial Analysis.


The contribution describes the experimental results obtained from the combined loading of the specimens in the field of high-cycle fatigue. Those

specimens were manufactured from common construction steel 11523. The following experiments were performed: The first set of the specimen was loaded by the alternating
torque amplitude. The second set was loaded by the alternating amplitude of the bending moment. The next set was loading by alternating amplitude of the torque and bending moment. This experiment was performed for two loading levels applied in the same phase. The results were evaluated by the conjugated strength criterion and another generally used multiaxial fatigue criteria. The stress-strain analysis of the specimens by FEM was performed to determine parameters (constants) of particular strength criteria.
