The role of microstructural dissimilitude in fatigue and fracture of small cracks
Kwai S. Chan,James Lankford +1 more
TLDR
In this paper, the specific effect of microstructural similitude on the crack driving force of both small and short, versus large, cracks is examined, and its relevance to small crack behavior illustrated by considering the dependence of the number of grains interrogated by the crack front on crack size and resulting yield strength variation within the crack tip process zone.About:

Defects as a root cause of fatigue failure of metallic components. I: Basic aspects
TL;DR: In this article, a three-part review is presented of defects which can cause failure in cyclically loaded structures. But the authors focus on defects that can be shown to cause failure by a quantitative analysis and that would not have occurred in the absence of the imperfections.
Journal ArticleDOI
Investigation of the effect of grain clusters on fatigue crack initiation in polycrystals
TL;DR: In this paper, the authors investigate the consequences of the local fields in a grain and propose an analysis, where the neighborhood of the grain also plays a significant role in fatigue crack initiation in ductile alloys like stainless steels.
Journal ArticleDOI
Stage I fatigue crack propagation in a titanium alloy
TL;DR: In this paper, the effects of crack orientation on Stage I fatigue behavior have been investigated by testing individual Widmanstatten colonies of the α-β Ti alloy Ti-8Al-lMo-lV in laboratory air and dry helium.
Journal ArticleDOI
Exfoliation Corrosion and Pitting Corrosion and Their Role in Fatigue Predictive Modeling: State-of-the-Art Review
TL;DR: In this article, a detailed discussion of cases where granular attack and exfoliation caused issues in structural integrity in aircraft in operational fleets is presented along with a much more detailed presentation of the issues involved in dealing with corrosion of aircraft.

The crystallography of fatigue crack initiation in coarse grained astroloy at 20°C
David L. Davidson,Kwai S. Chan +1 more
TL;DR: In this paper, the effects of crystallographic orientation on fatigue crack initiation was examined for coarse-grained Astroloy at 20°C by cycled by three-point bending at stress ranges between 5 and 95% of the proportional limit until fatigue cracks were detected.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Book ChapterDOI
The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.
Book
Elementary engineering fracture mechanics
D. Broek,James R. Rice +1 more
TL;DR: In this paper, the authors proposed a method to detect cracks in a crack-penetrization model, based on the Griffith criterion, which is used to detect the presence of a crack at a crack tip.
Book
Fracture Mechanics of Ceramics
TL;DR: In this article, a linear-elastic fracture mechanics can be applied to describe the failure behavior of small flaws in ceramic materials, which is caused by the extension of small faults.

XLVI. A theory of the plastic distortion of a polycrystalline aggregate under combined stresses.
J.F.W. Bishop,Rodney Hill +1 more
TL;DR: In this paper, a general relationship between stress and plastic strain in polycrystalline aggregate is derived for any metal in which individual crystals deform by slipping over preferred planes under a critical shear stress.
