As is well-known, non-proportional fatigue loading, such as asynchronous one, can have
significant detrimental effects on the fatigue behavior of metallic materials by reducing the …

A new approach based on the direct spectral method for fatigue analysis of elements
subjected to bimodal stress histories, including high compression effects, is proposed. A …

In this study, a novel test system for estimating bending and torsion fatigue under selectable
kinematic and dynamic loading modes was constructed. Using S355J2 steel specimens, a …

The torsional fatigue test determines the fatigue limit for a certain asymmetry coefficient of
the cycle. The assessment of fatigue tests is performed on specialized machines. There are …

The problem of multiaxial fatigue is considered from the standpoint of amalgamating
indicators of system reliability. The lifetime model is derived from the rule of amalgamating …

In this article, a torsional adapter is designed and evaluated through the comparison of
analytical, numerical, and experimental tools. The adapter converts a conventional tension …

This paper proposes an electro-hydraulic vibration control system based on the single-
neuron PID algorithm, which improves the operating frequency of the electro-hydraulic …

This paper reports the construction of a durability model of basic structures, which takes into
consideration the complex stressed state under the cyclic action of the complex load. The …

The object of the upgrade presented in this paper was an older analogue-based universal
testing machine preferably designed for tensile testing. The objective of the upgrade was to …

In order to solve the problem of large dynamic load and low loading accuracy prevailing in
traditional fatigue testing machines, and to meet the fatigue test loading demand of …
