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 Nucleation, Growth, and Arrest Under Subcritical Crack Growth
Transactions of the Indian Institute of Metals, 2015Component failures occur by crack initiation, growth and fast or overload fracture. The energetics demands that the crack tip driving forces must exceed the material resistance to crack growth. Crack being a high energy defect cannot nucleate spontaneously. However, it can nucleate in the presence of applied and localized internal stresses.

Crack growth of physically small cracks
International Journal of Fatigue, 2007This paper shows how, for physically small cracks, the unified crack growth model, also referred to as Unigrow, can be related to the generalized Frost and Dugdale crack growth model. We also show how this formulation can be used to predict the crack growth history of a range of experimental tests.

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 concise review is presented of widely used theories for the quantitative description of the growth of cracks in creeping media. Deficiencies are highlighted of the way in which calculations of component lifetimes have been carried out. New data is presented which overcomes some of the deficiencies, and results are presented of calculated component ...
