Non-Propagating Fatigue Cracks: The True Fatigue Limit [PDF]
, 1989 There are several reasons why fatigue cracks may cease to grow and hence need not be dangerous.

International Journal of Fatigue, 2012
Abstract The goal of this study was to confirm the presence of fatigue limit in a plain specimen of a new precipitation-hardened aluminium alloy. The alloy was fabricated by adding 0.53% excess Mg to the standard 6061-T6 aluminium alloy with a balanced Mg 2 Si composition.

On strain ageing and the fatigue limit
The Philosophical Magazine: A Journal of Theoretical Experimental and Applied Physics, 1970Abstract Metallographic evidence, provided by a low-carbon steel that was strain-cycled under varying conditions of strain ageing, has shown that active fatigue slip-bands are kept narrow when strain ageing is rapid but, in general, dislocations within the active bands are not captured by solute-locking.

Prediction of fatigue limit improvement in needle peened welded joints containing crack-like defects
, 2017Purpose The purpose of this paper is to estimate the acceptable defect size amax after needle peening (NP) and predict the fatigue limit improvement through the use of NP for an austenitic stainless steel welded joint containing an artificial ...

Measurement of Fatigue Limit in Silicate Glasses
2002Some studies on sub-critical growth in glass and ceramics have shown the existence of a lower limit of the applied stress intensity factor where the crack propagation tends to zero. This is usually defined as the fatigue limit or threshold stress intensity factor (K th ).Various testing methodologies have been suggested in the past for measuring this ...

Fatigue limit assessment for defective materials based on affected depth
, 2017In this study, a new fatigue limit assessment of defective materials submitted to acyclic loading is presented. This assessment is based on the analysis of the stress distribution in the vicinity of the defect.

Optimal Test Planning for the Fatigue-Limit Model When the Fatigue-Limit Distribution is Known
IEEE Transactions on Reliability, 2004This article discusses tools for planning life tests under the random fatigue-limit model, when the form of the fatigue-limit distribution is completely specified. Expressions for the Fisher information matrix elements are provided. Test-plan objectives, such as minimum variance of quantile or parameter estimator, can be written in terms of these ...
