      Fatigue crack growth and crack closure behavior of Ti‐6Al‐4 V alloy under variable‐amplitude loadings. in STP Advances in Fatigue Crack Closure Measurement and Analysis: Second Volume (eds.

    Figure Correlation of fatigue crack growth rates using the crack closure analysis (PNL1 steel). through the use of full field optical techniques to experimentally estimate 𝐾op, in order to confirm the results obtained in the inverse analysis of the proposed theoretical model. Many of the recent advances in the understanding of the fatigue crack growth process have resulted from an improved realization of the importance of fatigue crack closure in the crack growth process. Two basic crack closure processes have been identified. One of which is known as plasticity-induced fatigue crack closure (PIFCC), and the other is roughness-induced fatigue crack closure (RIFCC).Cited by: 2.

    Fatigue and fracture problems, which lead to 95% of structural failure, have attracted much attention of engineers and researchers all over the world. Compared with experimental method, numerical simulation method based on empirical models shows its remarkable advantages in structure design because of less cost and higher efficiency. However, the application of numerical simulation method in Author: Qiu Zhiping, Zhang Zesheng, Wang Lei.

Three-inch-wide ( mm) by inch-long ( mm) center-cracked specimens (Figure 2), oriented in the long transverse (TL) direction, were used in the fatigue crack growth File Size: 2MB.

The fundamental issue is that fatigue crack growth is sensitive to stresses nanometers in front of the crack tip, while the most broadly accepted closure measurement technique (the ASTM 2% offset standard [24, pp.

–90]) is typically only sensitive to closure 10 μm or more behind the crack tip. This is because the change in compliance with closure becomes smaller the closer closure is to the crack by: In book: Advances in Fatigue Crack Closure Measurement and Analysis: Second Volume, ASTM STPChapter: Role of Fatigue Crack Closure Stresses in Hydrogen-Assisted Cracking, Publisher.

As the load is increased, a critical value will be reached at which time the crack becomes open. Crack closure occurs from the presence of material propping open the crack faces and can arise from many sources including plastic deformation or phase transformation during crack propagation.
