| 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.
There has been realized a set of proportional and non-proportional experiments in the area of
high-cycle fatigue for basic methods of loading, namely: tension/compression, bending and torsion
and its mutual combinations. By selected experiments, the specimens were additionally loaded by
constant inner/outer pressure and axial prestress for a various loading levels. Experiments were
realized on testing machines, situated at author´s workplace. The experimental results were
undergone to application of selected and known criteria of fatigue strength and subsequently carried
out its modification according to the results. For gaining necessary input values for criteria of fatigue
strength, there was a need to realize a FEM simulation of test specimens.
