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.

Environmental Fatigue Crack Propagation Interactions
Canadian Metallurgical Quarterly, 1984Abstract Fatigue tests of G41400 Steel in laboratory air exhibited a large change in total life between summer and winter. Test frequency was also found to have a marked effect, with high moisture conditions causing increased sensitivity. The macro and micro fracture modes are shown to vary widely, being dependent upon the environmental conditions.

Fatigue failure is caused by the initiation of micro cracks from small defects in a material, followed by their propagation resulting in the formation of macro cracks, where the magnitude of applied stress may be lower than the yielding stress but the load is repeatedly applied to the material.

Crack propagation during fatigue experiments
International Journal of Fracture Mechanics, 1970In the present paper a very simple phenomenological theory of crack propagation during fatigue experiments is presented. It is shown that an important role is played by work-hardening to explain both the existence of a fatigue limit and the well known deviations from Miner's Rule in the case of tests conducted at varying maximum applied stresses ...

Fatigue crack propagation in concrete
International Journal of Fracture, 1989Numerous studies have been published on portland cement concrete fracture. But no attempt has been reported to relate the crack propagation rate in concrete to stress intensity factor range.

Modeling Corrosion Fatigue Crack Propagation
CORROSION 2001, 2001Abstract A mathematical model is proposed for modeling the chemistry and the potential distribution in a corrosion fatigue crack, along with the crack propagation rate, in sensitized stainless steel in boiling water reactor (BWR) coolant environments.

Corrosion Fatigue Crack Propagation
1983There is a cogent argument for the proposition, illustrated in Figure 1, that there is a spectrum of rate-determining steps in environmentally-controlled subcritical crack propagation encompassed by the phenomena ‘corrosion-fatigue’ (C.F.), ‘hydrogen-embrittlement’ (HE) and’ stress-corrosion cracking’ (SCC).
