Short fatigue cracks are the linkage of the initiation stage to the long crack growth which can be described by linear elastic fracture mechanics. Because some cracks can initiate then cease to grow, short cracks are important in the definition of fatigue limits.

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).

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.

Abstract This article describes the types of closure mechanisms, including plasticity-induced, roughness-induced, oxide-induced, and fretting-debris-induced. It discusses test techniques used to establish a valid threshold value for aluminum alloy crack growth thresholds, steel crack growth thresholds, and titanium alloy crack growth ...

In relation to fatigue crack growth, it is observed that long cracks under mixed mode loading conditions branch to follow the direction along which \(\Delta k_{\text{II}}\) is zero, but some results against this local symmetry criterion are also reported.

Engineering Fracture Mechanics, 1991
Abstract A loading stage for the scanning electron microscope has been used in conjunction with the stereoimaging technique to study fatigue crack closure for a center notched specimen of an aluminum alloy. The results are compared to similar measurements from single edge notched specimens of the same alloy and other materials.

Determination of Fatigue Crack Paths
International Journal of Bifurcation and Chaos, 1997The complete solution of the problem of a fatigue crack growing from an initial crack includes determination of the crack path. Macroscopic aspects of the main features of the path taken by a growing fatigue crack in a metallic material are reasonably well understood in a qualitative sense.

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.
