<div class="htmlview paragraph">The effects of single and multiple tensile overloads on precracked center-notched sheet specimens of Ti-8 Al-1 Mo-1V titanium alloy were investigated under laboratory conditions. Single tensile overloads always delayed subsequent fatigue crack growth at lower stress levels. Multiple tensile overloads caused a delay

The growth of fatigue cracks in aluminium
International Journal of Fracture Mechanics, 1971Experiments have been performed in order to assess quantitatively the rates of fatigue crack propagation in metals. Low stress fatigue tests have been performed on aluminium specimens under conditions of constant load and constant stress. The crack growth rates are found to be proportional to the fourth power of the appropriate stress intensity factors.

Fatigue Crack‐Growth Reliability
Journal of Engineering Mechanics, 1990A method is shown for estimating the reliability of structural components subject to fatigue crack growth. The method is general in that it can be used in conjunction with any crack-growth law and either first- or second-order reliability techniques. The initial crack length, final crack length, and crack-growth parameters are taken as uncertain with ...

XCVIII. The growth of fatigue cracks
The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, 1953Summary The qualitative features of the growth of a fatigue crack are discussed. A model is proposed whichh as these features and from which quantitative predictions can be made. These are in satisfactory agreement with experimental measurements. It is concluded that cracks may be formed at an early stage in fatigue and that the growth of a crack may ...

Fatigue Crack Growth and Applications
2001The traditional approach for estimating the total life of a structural part, when it is subjected to a load varying environment, is to use the S-N diagram (alternating stress, S, versus the total number of cycles to failure, N). The S-N diagram for high cycle fatigue is constructed using the ASTM E-466 Standard.

Modelling of Fatigue Crack Growth
1989Fatigue crack growth is presently being treated almost exclusively within the theoretical framework of fracture mechanics. This trend is following the pioneering work of Paris and his co-workers, which date back some 25 years (1). However, at that time several other parameters than K, the stress intensity factor, were being used to correlate fatigue ...
