TL;DR: In this article, the threshold in the alternating range of stress intensity factor for fatigue crack growth is investigated for 2024-T3 aluminum, and it is seen to decrease with increasing frequency at a fixed load ratio, dropping by nearly a factor of 2 from 342 to 832 Hz.
Abstract: The threshold in the alternating range of stress intensity factor for fatigue crack growth is investigated for 2024-T3 aluminum. Testing techniques provided displacement control at frequencies up to 1000 Hz. The thresholdis seen to decrease with increasing frequency at a fixed load ratio, dropping by nearly a factor of 2 from 342 to 832 Hz. The threshold is also observed to decrease with increasing load ratio in such a way that is tentatively explained by considerations of crack closure. Some confirmation of this is obtained from direct strain gage measurement of the closure stress intensity, K c , which agrees with that predicted from trends in the threshold data with respect to load ratio.

TL;DR: In this paper, the authors investigated the influence of mean stress, specimen thickness, flow stress, and fracture toughness on the growth rate of fatigue crack propagation through their effect on growth mechanism and showed that simple relationships between the rate of propagation and alternating stress intensity are adequate for describing fatigue crack growth.

TL;DR: In this article, fatigue crack growth in an elastic-perfectly plastic solid is modelled using a two-dimensional finite element analysis, where plane deformations are enforced and crack advance is simulated by node release.

TL;DR: In this article, the current state of the art in terms of plastic localization, damage, static and fatigue cracking for three classes of systems: (1) bulk ultra-fine grained and nanocrystalline metals, (2) thin metallic films on substrates, and (3) 1D and 2D freestanding micro and nanoscale systems.

Journal ArticleDOI
TL;DR: In this paper, the authors examined the basis of similitude for the strain energy release rate range and how it can be redefined in order to avoid potential misinterpretations of fatigue delamination growth.
