Unraveling the Science of Variable Amplitude Fatigue

Journal of ASTM International, 2011
Abstract Conventional methods to estimate variable-amplitude fatigue life revolve either around cumulative damage analysis using the local stress-strain approach, or, around one of the crack growth load interaction models. Despite advances in modeling the mechanics of fatigue, none of these methods can faithfully reproduce the near ...

The Significance of Variable Amplitude Fatigue Testing

1994
Experimental fatigue and durability assessment plays a prominent role in light-weight design. There is broad evidence, however, that the fatigue strength of materials and structures determined under constant amplitude loading may be not relevant—quantitatively or even qualitatively—for variable amplitude or spectrum loading. Various phenomena both on a

Prediction uncertainties at variable amplitude fatigue

International Journal of Fatigue, 1997
Abstract Predictions of variable amplitude fatigue life suffer from uncertainties originating from different sources. In this paper, important sources are discussed and estimated, by means of a variable amplitude fatigue model, based on level crossing counts and a version of the Palmgren–Miner cumulative damage rule.

Methodology of Variable Amplitude Fatigue Tests

1989
Fatigue life prediction by experiment, that is variable amplitude testing, is becoming more and more widespread in industry. The many engineering decisions necessary before a useful variable amplitude test can be carried out are explained in detail, such as measurement of the stress time history in service which couting procedure to use and ...
