Multiaxial fatigue life and strength criteria for non-proportional loading*
Abstract
In the article a proposal of loading non-proportionality measure H for sinusoidal biaxial loading has been presented. On the basis of non-proportionality measure, there has been proposed a bending and torsional fatigue strength, with a phase shift of components and the mean value has been proposed. Moreover, a high-cycle fatigue life criterion based on the same non-proportionality measure has been proposed. The predictive capability of both criteria were demonstrated by analysing experimental results from the literature. The predicted results are generally in good agreement with the experimental ones.
Kurzfassung
Im vorliegenden Beitrag wird ein Ansatz für die Messung der nicht-proportionalen sinusförmigen multiaxialen Beanspruchung vorgestellt. Auf der Basis der nicht-proportionalen Messung wird ein Kriterium für die Ermüdungsfestigkeit bei Biegung und Torsion propagiert unter Angabe der Phasenverschiebung von Komponenten und des Hauptwertes. Darüber hinaus wird ein Lebensdauerkriterium für hochfrequente Ermüdung basierend auf derselben nicht-proportionalen Messung propagiert. Die Vorhersagbarkeit beider Kriterien wird durch die Analyse von Literaturangaben demonstriert. Die vorhergesagten Ergebnisse stimmen mit den experimentellen Ergebnissen überein.
