This chapter explains the fatigue damage growth phenomena in FMLs, and provides theories to describe the growth of damage based on the individual fracture phenomena. The validity of various geometrical correction factors is discussed. The different crack geometries through-thickness and the crack paths, observed in FMLs, are explained for both in-axis ...

International Journal of Fracture, 1979
While currently used criteria for onset of crack propagation in a mixed mode loading situation give different predictions for the angle of incipient branching, the present paper demonstrates that the trajectory of a curved crack to a large extent is independent of the choice among these criteria.

How Fast Can Cracks Propagate?
Physical Review Letters, 2000We have performed atomic simulations of crack propagation along a weak interface joining two harmonic crystals. The simulations show that a mode II shear dominated crack can accelerate to the Rayleigh wave speed and then nucleate an intersonic daughter that travels at the longitudinal wave speed.

Cosserat Models Versus Crack Propagation
Mathematics and Mechanics of Solids, 2003In this paper, we analyze the consequences of Sih’s fracture criterion in a material which behaves according to the Cosserat-type model with free or constrained rotations. Both models are considered and for each of them the first and the second fracture mode is analyzed. To apply Sih’s criterion, the singular part of the stress field and of the couple

Journal of Basic Engineering, 1971
This study is concerned with the application of Griffith fracture theory to crack propagation induced by thermal means. The stress-strain field around an insulated crack, situated perpendicular to a uniform flow of heat in an elastic medium, is extracted from an isothermal configuration in which the crack surfaces are subjected to linear shear stresses.

Fatigue Crack Propagation of Short Cracks
Journal of Engineering Materials and Technology, 1979Previous studies have shown that both threshold stress intensity factors and fatigue crack growth rates are dependent on crack size. The average growth rates for very short cracks considerably exceed those given by conventional stress intensity-crack growth laws fitted to long crack data.

Crack Propagation in Finite Elastodynamics
Mathematics and Mechanics of Solids, 2005Within the framework of finite elastodynamics, a crack propagation analysis, for sheets of compressible hyperelastic material, is formulated. By exploiting a dynamic generalization of the Stephenson's result, general far-field loading conditions are considered.

The Propagation of Fatigue Cracks
Journal of Applied Mechanics, 1956Abstract A theory of the rate of growth of fatigue cracks is extended to the case of large stresses. Recent measurements of McClintock and Ryan are discussed.

Dynamic instability in crack propagation
Physical Review E, 1994A linear stability analysis of the steady state solutions to a model for propagating cracks implies dynamic instability beyond a critical crack speed, oscillatory behavior of the crack tip velocity, and the emergence of spatial structure. The results are in qualitative agreement with experiment.
