Fatigue in materials subjected to repeated cyclic loading can be defined as a progressive failure due to crack initiation (stage I), crack growth (stage II), and crack propagation (stage III) or instability stage. For instance, crack initiation of crack-free solids may be characterized by fatigue crack nuclei due to dislocation motion, which generates ...

In this chapter we will first present a synopsis of the theoretical foundation of linear and nonlinear fracture mechanics. In recent years a number of monographs, textbooks and conference proceedings have been published on the subject of fracture mechanics (see for example [1–10] where further references are listed).

Multiple-cracked fatigue crack growth by BEM
Computational Mechanics, 1995The dual boundary element method is applied to the two-dimensional linear elastic analysis of fatigue problem of multiple-cracked body. For each crack, the traction integral equation is applied on one surface of the crack, while the usual displacement integral equation is used simultaneously on the other. General multiple crack growth problem is solved

Crack patching: Predicting fatigue crack growth
Theoretical and Applied Fracture Mechanics, 2006This paper examines the crack growth history of a range of test specimens, and cracks repaired with a composite patch, and shows that in the low to mid range ΔK region there is a near linear relationship between the log of the crack length and the number of cycles.

A fatigue crack growth threshold
Engineering Fracture Mechanics, 1992Abstract Fatigue crack growth (FCG) threshold has been determined on Ti6A14V, Al 7475-T7351, quenched and tempered steel 24CrMo4 as well as on the Ni-base alloys Inconel 617 and Nicrofer 5219 Nb. The main objective of the studies was to prove the transferability of the experimentally determined FCG threshold to service type fatigue loading.

Thermomechanical fatigue crack growth
International Journal of Fatigue, 1996This paper investigates the behaviour of thermomechanical fatigue crack growth using the dual boundary element method. Crack growth is simulated by using an incremental crack extension in a direction determined by the maximum principal stress criterion, which is expressed in terms of the total stress intensity factors.

Fatigue Crack‐Growth Reliability
Journal of Engineering Mechanics, 1990A method is shown for estimating the reliability of structural components subject to fatigue crack growth. The method is general in that it can be used in conjunction with any crack-growth law and either first- or second-order reliability techniques. The initial crack length, final crack length, and crack-growth parameters are taken as uncertain with ...

Automatic Fatigue Crack Growth
Volume 6: Materials and Fabrication, Parts A and B, 2009One of the critical requirements of fatigue crack growth simulation is calculation of the remaining life of a structure under cyclic loading. This paper presents a method which predicts the remaining fatigue life of a part, and gives information on the eventual mode of failure.
