The Merging of Fatigue and Fracture Mechanics Concepts: A Historical Perspective
TLDR
Small-crack theory has unified “fatigue” and “fracture mechanics” concepts; and has bridged the gap between safe-life and durability/damage-tolerance design concepts, so that fatigue damage can now be characterized by “crack size”.About:

A generalized Paris' law for fatigue crack growth
TL;DR: In this article, an extension of the celebrated Paris law for crack propagation is given to take into account some of the deviations from the power-law regime in a simple manner using the Wohler SN curve of the material, suggesting a more general ''unified law''.
Journal ArticleDOI
A state-of-the-art review on fatigue life prediction methods for metal structures
TL;DR: In this article, a state-of-the-art review of metal fatigue is carried out, with particular emphasis on the latest developments in fatigue life prediction methods, including material, structure, loading, and environment.
Book ChapterDOI
Fatigue and Fracture
TL;DR: In this article, the suitability and uncertainty of physical models were considered for crack initiation and growth under cyclic loading as well as unstable crack propagation and tearing in ship and offshore structures and due attention was paid to practical application and statistical description of fracture control methods in design, fabrication and service.
Journal ArticleDOI
About the fatigue crack propagation threshold of metals as a design criterion – A review
Uwe Zerbst,Michael Vormwald,Reinhard Pippan,Hans-Peter Gänser,Christine Sarrazin-Baudoux,Mauro Madia +5 more
TL;DR: The fatigue crack propagation threshold ΔKth is of paramount importance for any kind of damage tolerant design, but in contrast to this importance, the determination and application of the parameter is not on the firm ground as previously assumed.
Journal ArticleDOI
A framework to model the fatigue behavior of brittle materials based on a variational phase-field approach
TL;DR: In this paper, a variational framework to model the fatigue behavior of brittle materials based on a phase-field approach to fracture is presented, where the standard regularized free energy functional is modified introducing a fatigue degradation function that effectively reduces the fracture toughness as a proper history variable accumulates.

A Path Independent Integral and the Approximate Analysis of Strain Concentration by Notches and Cracks
TL;DR: In this paper, an integral is exhibited which has the same value for all paths surrounding a class of notches in two-dimensional deformation fields of linear or non-linear elastic materials.
Journal ArticleDOI
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.

On the ductile enlargement of voids in triaxial stress fields
James R. Rice,D.M. Tracey +1 more
TL;DR: In this article, a variational principle is established to characterize the flow field in an elastically rigid and incompressible plastic material containing an internal void or voids, and an approximate Rayleigh-Ritz procedure is developed and applied to the enlargement of an isolated spherical void in a nonhardening material.
