Multiaxial fatigue life assessment in notched components based on the effective strain energy density

Prediction of Fatigue Life in Notched Specimens Using Multiaxial Fatigue Criteria

In this research, the effects of notch shape on the fatigue strength of 2024-T3 aluminum alloy notched specimens have been studied using experimental and multiaxial fatigue analysis. For this purpose, four set of specimens with different notch shape were prepared and then fatigue tests were carried out at various cyclic longitudinal load levels. Load controlled fatigue tests of mentioned specim...

A New Strain Based Model for Predicting Multiaxial Fatigue Life of Metals

Engineering structures are usually exposed to cyclic multiaxial loading and subsequently to multiaxial fatigue. Different models and criteria with various capabilities have been proposed for predicting of multiaxial fatigue life. Selection of proper model by considering material, type of loading and operation condition of each engineering structure is a challenging issue of the life prediction ...

On the Effectiveness of a Multiaxial Fatigue-Life Predictive Method Based on a Virtual Strain-Energy Concept

Assessment of the Existing Models to Estimate the Fatigue Life under both Multiaxial in Phase and 90° Out of Phase Loading Conditions

Engineers have a range of methods to estimate the fatigue life under multiaxial conditions. Each of these predictive methods is generally subjected to restrictions, related to the inherent simplified assumptions. The objective of this paper is to evaluate the validity of commonly used multiaxial fatigue criteria for different multiaxial loading conditions. The best criterion is identified throu...
