TL;DR: In this article, the effects of specimen thickness on crack tip deformation and fatigue crack growth rate (FCGR) were investigated on the specimens of Type 304 stainless steel and Inconel 718.

TL;DR: In this paper, a study on the behavior of crack propagation rate as a function of R ratio, from negative to positive stress ratios, is made, where both the effect of P max and of R ratios are taken into consideration.

TL;DR: In this paper, a micromechanical description of the fatigue crack growth process at notches is presented, and the formation of non-propagating cracks is also explained.
Abstract: A micromechanical description of the fatigue crack growth process at notches is presented. Crack interaction with the plastic slip barriers of the material (e.g. grain boundaries) and the influence of the notch stress gradient are intrinsically taken into account in the model. Both the notch fatigue crack initiation limit and the limit for propagation up to failure (i.e. the conventional notch fatigue limit) are clearly identified and calculated. The formation of non-propagating cracks is also explained.

TL;DR: In vitro cyclic fatigue experiments were conducted over a range of cyclic frequencies on elephant dentin in order to quantify fatigue-crack growth behavior from the perspective of understanding the mechanism of fatigue in dentin, finding results obtained to be of importance for an improved understanding of fatigue-related failures in teeth.
