TL;DR: In this article, a multilinear model of the cyclic plastic zone model of fatigue crack growth was proposed. But the model was not applied to the case of aluminum alloys, and it was shown that transition to the threshold for fatigue crack formation is controlled by dispersoid particles.

TL;DR: In this paper, the authors examined the influence of austempering heat treatments and the resultant microstructure of alloyed nodular ductile cast iron on the fatigue crack growth rate, fatigue threshold, and high-cycle fatigue strength of the material.

TL;DR: In this paper, a single overload (OL) was applied to a ductile austenitic CrNi alloy and fractographic observations indicated an increased crack growth rate in a small number of cycles after the application of the OL.

TL;DR: In this article, a cumulative strain induced crystallization process is proposed to explain the stress ratio effect on fatigue crack initiation and propagation properties of natural rubber, and it is shown that the reinforcement process is associated with strong crack branching in the crack tip region.
Abstract: Natural rubber is known to have excellent fatigue properties. Fatigue crack propagation studies show that, under uniaxial tension loading, fatigue crack growth resistance increases with the loading ratio, even if the peak stress increases. Studies dealing with crack initiation confirm this trend. If strain induced crystallization is believed to play a major role in this reinforcement process, it is not clear yet by which mechanism this reinforcement takes place. Using SEM investigation, it is shown here that the reinforcement process is associated with strong crack branching in the crack tip region. From experimental results it is shown that under particular reinforcing loading condition a cyclic strain hardening process can be observed on the natural rubber which is able to overcome classically observed softening effects. A cumulative strain induced crystallization process is proposed to explain the stress ratio effect on fatigue crack initiation and propagation properties of natural rubber.

TL;DR: In this paper, emissions from fatigue crack growth have been examined for three steels (A533B steel, low carbon steel and H1 weld metal) using ACEMAN, a system for acoustic emission source location and analysis.
