Modeling of Fatigue Crack Propagation

Journal of Engineering Materials and Technology, Transactions of the ASME, 2004
Fatigue 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.

Fatigue Crack Propagation

2017
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 ...

Fatigue Crack Propagation of Short Cracks

Journal of Engineering Materials and Technology, 1979
Previous 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.

Fatigue crack propagation. Report 2. A crack propagation model

Strength of Materials, 1988
1. A model of fatigue crack propagation was proposed; the model is based on determining the specific energy of inelastic strain cumulated at the distance X* from the crack tip, with an allowance made for the energy irreversibly scattered within the scope of the zone of damageRm (Rm≥X*). 2.

Fatigue crack propagation in maragingsteel

Materials Science and Technology, 1997
AbstractFatigue crack growth behaviour in different conditions of maraging (350) steel was studied at a stress ratio R = 0.1, at a constant applied stress level. The slope m in the Paris region was found to be almost the same in the annealed and aged conditions.

The Propagation of Fatigue Cracks

Journal of Applied Mechanics, 1956
Abstract 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.
