Fatigue Crack Propagation of Short Cracks
Journal of Engineering Materials and Technology, 1979Previous studies have shown that both threshold stress intensity factors and fatigue crack growth rates are dependent on crack size. The average growth rates for very short cracks considerably exceed those given by conventional stress intensity-crack growth laws fitted to long crack data.

Fatigue crack propagation. Report 2. A crack propagation model
Strength of Materials, 19881. A model of fatigue crack propagation was proposed; the model is based on determining the specific energy of inelastic strain cumulated at the distance X* from the crack tip, with an allowance made for the energy irreversibly scattered within the scope of the zone of damageRm (Rm≥X*). 2.

Secondary cracking process during fatigue crack propagation
Engineering Fracture Mechanics, 1973Abstract Using the scanning electron microscope, fatigue striations in secondary microcracks normal to the main fatigue cracks have been observed on fracture surfaces of fatigue specimens made from 2024 and 2618 aluminium alloys, a Ti-6A1-V titanium alloy, and an Incolloy 901 nickel-base refractory alloy.

Fatigue Crack Propagation in Metals
Nature, 1966PEARSON1 has recently discussed the problem of the rate of growth of a fatigue crack. He tabulated values of the stress intensity factor K necessary to cause a crack to grow under a repeated tensile loading cycle at a certain velocity in a number of alloys and showed that the ratio of K to the Young's modulus E of the material was roughly constant. The

Modeling Environment-Assisted Fatigue Crack Propagation
2008Predicting fatigue crack growth in metals under random loadings remains difficult since fatigue crack growth is very sensitive to load history. Load history effect in fatigue is known for decades to stem from plastic deformation in the vicinity of the crack tip.

Fatigue crack propagation in polyacetal
Journal of Materials Science, 1978The fatigue crack propagation characteristics of a typical commercial homopolymer and copolymer polyacetal were determined. These materials were found to be the most fatigue resistant plastics examined to date, thus confirming the generally high fatigue resistance of all crystalline polymers.

Fatigue crack propagation in maragingsteel
Materials Science and Technology, 1997AbstractFatigue crack growth behaviour in different conditions of maraging (350) steel was studied at a stress ratio R = 0.1, at a constant applied stress level. The slope m in the Paris region was found to be almost the same in the annealed and aged conditions.

The Propagation of Fatigue Cracks
Journal of Applied Mechanics, 1956Abstract A theory of the rate of growth of fatigue cracks is extended to the case of large stresses. Recent measurements of McClintock and Ryan are discussed.

The determination of the fatigue crack propagation curve is an essential part of the fracture mechanics design approach. Residual strength calculation procedures have obvious shortcomings, but the prediction of fatigue crack propagation characteristics is even less accurate, despite the vast amount of research that has been done on this subject.
