Thermomechanical Fatigue Life Prediction of Notched

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...

Lifetime prediction in creep-fatigue environment

The creep-fatigue interaction has been studied and innovative mathematical models are proposed to predict the operating life of aircraft components, specifically gas turbine blades subject to creep-fatigue at high temperatures. The historical evolution of the creep-fatigue lifetime prediction is given in order to place the present study in the context. A literature review of the life estimation...

Lifetime prediction of adhesive joints subjected to variable amplitude fatigue

Almost all structural applications of adhesive joints will experience cyclic loading and in most cases this will irregular in nature, a form of loading commonly known as variable amplitude fatigue (VAF). This paper is concerned with the VAF of adhesively bonded joints and has two main parts. In the first part, results from the experimental testing of adhesively bonded single lap joints subjecte...

A Benchmark on Lifetime Prediction of Composite Materials under Fatigue

The present paper describes a benchmarking programme to compare different lifetime prediction methodologies. Lifetime prediction is still a complex task and the results depend on many factors. Thus, it is very important to know which factors have a decisive effect on the results. The main objective of this investigation is not to proof the validity of a certain prediction model, but to quantify...
