Modeling of Fatigue Crack Propagation
Journal of Engineering Materials and Technology, 2004Fatigue crack propagation was modeled by using the cyclic plasticity material properties and fatigue constants for crack initiation. The cyclic elastic-plastic stress-strain field near the crack tip was analyzed using the finite element method with the implementation of a robust cyclic plasticity theory.

A model for fatigue crack closure
Engineering Fracture Mechanics, 1984Abstract The phenomenon of fatigue crack closure has attracted continued interest over recent years. This paper concerns itself with one aspect of the phenomenon namely the effects of a single asperity on the crack face close to the crack tip and under dominantly plane strain Mode 1 loading conditions.

ADAPTIVE AND HIERARCHICAL MODELING OF FATIGUE CRACK PROPAGATION
34th Structures, Structural Dynamics and Materials Conference, 1993AbstractA methodology is developed to simulate adaptively and hierarchically fatigue crack growth in structural components. Cracks are modelled, by overlaying portions of the finite element mesh free of cracks with a discontinuous finite element field containing unconstrained double nodes along the discontinuity.

A NOTE ON MODELLING SHORT FATIGUE CRACK BEHAVIOUR
Fatigue & Fracture of Engineering Materials & Structures, 1998Based upon experimental short fatigue crack growth data and adopting the Brown–Hobson model, new crack growth equations have been derived in an attempt to describe more precisely short fatigue crack growth behaviour that separates the physically small crack regime from the long crack regime.

A model of the environmentally affected growth of fatigue cracks
Journal of Applied Mathematics and Mechanics, 1998The authors discuss the processes of the damage accumulation and cracks growth under combination of the cylindrical loads and corrosion fatigue. The known correlations of equilibrium and balance of energy in the system ``body with cracks -- load'' are completed with the equations describing the processes of the damage accumulation near the crack edges ...

On a model of small fatigue cracks
Engineering Fracture Mechanics, 1987Abstract A simple model is proposed, which allows one to explain and describe quantitatively the peculiarities of the kinetics of small fatigue cracks growth. The characteristics of material microstructure are introduced into consideration explicitly as well as those of the fields of microstress induced by the material microstructure.

Modeling Environment-Assisted Fatigue Crack Propagation
2008Predicting fatigue crack growth in metals under random loadings remains difficult since fatigue crack growth is very sensitive to load history. Load history effect in fatigue is known for decades to stem from plastic deformation in the vicinity of the crack tip.

A probabilistic model for fatigue crack growth
Engineering Fracture Mechanics, 1992Abstract A probabilistic model for predicting fatigue crack growth rate and cycles to reach a given crack length is presented. The stochastic characterizations of crack growth parameters c and m in the Paris-Erdogan and Forman laws are investigated based upon crack growth experiments.

Validation of a peridynamic model for fatigue cracking
Engineering Fracture Mechanics, 2016Abstract Fatigue cracking in homogeneous and in composite materials is studied using a peridynamic model. We introduce a set of critical damage factors that improve stability and efficiency of a recently introduced peridynamic model for fatigue cracking.
