TL;DR: In this article, the authors examined the crack growth history of a range of test specimens, and cracks repaired with a composite patch, and showed 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.

TL;DR: In this article, the authors examined the fatigue crack growth histories, at low K's, of a range of test specimens and service loaded components and concluded that there is a linear relationship between the log of the crack length or depth and the service history (number of load cycles).

TL;DR: In this article, the authors presented an overview of the finite element alternating technique for the analysis of interacting cracks, which is used to analyse several problems associated with both widespread fatigue and multi-site damage, a problem which is attracting worldwide attention.

TL;DR: In this article, the authors present the results of an extensive experimental analysis of the fractal properties of fatigue crack rough surfaces, which leads to a particularization of the fatigue crack growth equation based on fractality proposed by the last two authors.

TL;DR: In this article, a 3D biological algorithm that uses fracture parameters as the design criteria was presented for shape optimisation of structures with fracture strength as a design objective, and it was found that the optimum hole shapes were approximately elliptical with the aspect ratios being dependent on crack sizes, structural geometry and boundary conditions.
