An investigation on fatigue crack growth rates through a designed nonsymmetric crack growth test

Engineering Fracture Mechanics, 2012
A nonsymmetric fatigue crack growth (FCG) test is specially designed and performed to study whether FCG test data from nonsymmetric cracking which is unavoidable in practice can be used to determine valid FCG rate information for fatigue life evaluation.

Prediction of fatigue crack growth rates based on crack blunting

Engineering Fracture Mechanics, 1994
Abstract An energy approach is taken to predict fatigue crack growth rates. By including the strain energy released by crack blunting, an expression for fatigue crack growth is derived that depends upon the applied ΔK and the material's modulus, yield strength and fracture toughness.

THE RELATION BETWEEN CRACK BLUNTING AND FATIGUE CRACK GROWTH RATES

Fatigue & Fracture of Engineering Materials & Structures, 1994
Abstract— Previous work has shown that the inclusion of the strain energy released by crack blunting leads to an energy minimum for fatigue crack growth that can be used to predict stage II fatigue crack growth. The present work assumes a polynomial relation between crack blunting and crack extension to derive an expression for the rate of fatigue ...

Fatigue Crack Growth Rate Testing of Gun Steels

Journal of Pressure Vessel Technology, 1986
Abstract The experimental measurement of fatigue crack growth rates is an integral part of the fracture mechanics approach to safe life estimation in structures subjected to cyclical loading. To assess the variation in crack growth properties, data has been collected from five different gun steels from various sources.

Fatigue Crack Growth Rate Under Irregular Fatigue Loading

2003
An aircraft cracked component can be approximated as a wide plate with a centre-crack. The component is subjected to the following repeated load sequence: 5, 120, 15, 91, 18, 75, 40, 80, 10, 110 MPa. A crack of length 20 mm has been detected in the component.

Fatigue Crack Growth Rates as a Function of Temperature

1981
The equation dadN=C[(KlG−Klmin)+ΔKT][(Klmax−KIG)−ΔKT]2 had been proposed by the author to predict fatigue crack growth rates. By adopting this functional relation and setting KIG = 0.5 KImax (KIG ∼ KIopen under constant-amplitude cyclic loading), there are the two parameters, C and ΔKI, left to be determined from experimental data.
