Mechanisms of fatigue-crack propagation in ductile and brittle solids
TL;DR: In this article, the authors examined the mechanisms of fatigue-crack propagation with particular emphasis on the similarities and differences between cyclic crack growth in ductile materials such as metals, and corresponding behavior in brittle materials, such as intermetallics and ceramics.
Journal ArticleDOI
Microstructural effects on the mechanical behavior of B-modified Ti–6Al–4V alloys
TL;DR: In this paper, microstructural properties of hot isostatically pressed Ti-6Al-4V alloy with 0, 0.05, 0., 10, and 0.40 wt.% B additions have been examined, with particular emphasis on identifying the micro-structural length scale (grain size vs. lath size) that controls the mechanical properties of these alloys.
Journal ArticleDOI
Influence of microstructure on high-cycle fatigue of Ti-6Al-4V: Bimodal vs. lamellar structures
TL;DR: In this article, the authors examined how the overall resistance to high-cycle fatigue in Ti-6Al-4V compares between the bimodal microstructure and a coarser lamellar (β-annealed) micro-structure.
Journal ArticleDOI
Fracture toughness and fatigue crack growth characteristics of nanotwinned copper
TL;DR: In this article, the effect of twin density on the crack initiation toughness and stable fatigue crack propagation characteristics of nano twinned copper (NT Cu) was investigated, and the effects of tailored density of nanotwins, incorporated into a fixed grain size of ultrafine-grained (UFG) copper with an average grain size, on the onset and progression of subcritical fracture under quasi-static and cyclic loading at room temperature.
Journal ArticleDOI
An experimental evaluation of fatigue crack growth
TL;DR: In this paper, the authors examined the fatigue crack growth histories of a range of test specimens and service loaded components and concluded that in all cases, the crack growth shows, as a first approximation, a linear relationship between the log of the crack length or depth and the service history (number of cycles).

TL;DR: In this article, a finite element solution to the large-scale yielding of a circumferentially cracked round tension bar is obtained, and the three-dimensional aspects of flawed structures and numerical methods of treating them are studied.
Journal ArticleDOI
Linear fracture mechanics, fracture transition, and fracture control
TL;DR: In this article, the leading edge of a crack is treated as a line disturbance zone in a manner similar to the treatment of dislocation lines in dislocation mechanics, and the authors discuss interpretation of the brittle-ductile transition in terms of relative plastic zone size, and allowable load estimates which include fracture strength in a rational way.
