Fatigue crack growth in polymers
International Journal of Fracture, 1980A number of fatigue crack propagation laws applied in the study of polymers is described. Consideration of the stress field distribution at the crack tip leads to the application of fracture mechanics. It is shown that a simplified relationship of the form da/dN =Fλα, whereφ is a function ofKIC,Kmax,Kmin andKTH appears to be a convenient expression for

SAE Technical Paper Series, 1974
<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

Fatigue Crack Growth, Fatigue, and Stress Corrosion Crack Growth: Section XI Evaluation
2012AbstractFatigue has often been described as the most common cause of failure in engineering structures, and designers of pressure vessels and piping have incorporated fatigue considerations into design requirements since the first edition of Section III in 1963.

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 ...
