Fatigue Crack Initiation—Propagation Reliability Model

Journal of Materials in Civil Engineering, 1991
The paper presents a probabilistic model for fatigue strength that includes both the initiation and propagation phases, and is suitable for inclusion of formal reliability analyses. This method is most useful for fatigue in a fabricated structure that is expected to have a small crack initiation life and may apply to a significant body of welded joint ...

Modelling plasticity-induced fatigue crack closure

Engineering Fracture Mechanics, 1990
Abstract A numerical analysis of plasticity-induced fatigue crack closure based upon the finite difference method is presented. This new method permits modelling easily fatigue crack growth as well as contacts between fracture faces, without requiring sophisticated algorithms.

Stochastic Modeling of Fatigue Crack Propagation

1985
Deterministic fatigue crack propagation models, such as the Paris-Erdogan model, cannot account for random variability of time-histories observed in experiments. Therefore, more realistic models are proposed in which a random process is introduced as a multiplicative factor to deterministic laws.

Stochastic models of fatigue crack growth

Engineering Fracture Mechanics, 1989
Abstract A number of stochastic models of fatigue crack growth under constant amplitude cyclic loading are assessed in the light of experimental data. Particular attention is paid to the predictive performance of the models under a change in the initial crack length and generally it is found that the models provide a poor estimate of the standard ...

Analytical modelling of fatigue crack propagation

Fatigue & Fracture of Engineering Materials & Structures, 1999
An analytical approach to the prediction of fatigue crack growth is discussed from the viewpoint of analytical mechanics and mechanics of solids. Conditions of fatigue crack non‐propagation and stability are formulated in terms of the principle of virtual work for systems with unilateral constraints.

Stochastic Modelling of Fatigue Crack Growth

1985
The paper is devoted to modelling and analyzing of the fatigue process via stochastic differential equations resulting from randomization of experimental fatigue crack propagation laws. After brief discussion of some experimental results concerning fatigue crack growth the questions of randomization of experimental laws and stochastic fatigue growth ...

Modelling of random fatigue crack growth

Engineering Fracture Mechanics, 1986
Abstract The paper is concerned with stochastic modelling of fatigue crack growth under random loading and other uncertainties. The model proposed takes into account experimental results and existing theoretical hypotheses concerning fatigue crack growth.
