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.

Metal fatigue is a major cause for failure of mechanical and structural components. We review the fracture mechanics of fatigue and Paris-Erdogan law for the mean behavior. After a consideration of experimental data reported by Virkler et al. (1979), we propose a continuous semimarkov process to model crack growth.

<div class="htmlview paragraph">The effects of single and multiple tensile overloads on precracked center-notched sheet specimens of Ti-8 Al-1 Mo-1V titanium alloy were investigated under laboratory conditions. Single tensile overloads always delayed subsequent fatigue crack growth at lower stress levels. Multiple tensile overloads caused a delay

AbstractThis article describes the fracture mechanics in fatigue. It discusses the fatigue crack growth rate (FCGR) testing that consists of several steps, beginning with selecting the specimen size, geometry, and crack length measurement technique. The two major aspects of FCGR test analysis are to ensure suitability of the test data and to calculate ...
