Statistical Modeling of Fatigue Crack Growth

open access: yesJournal of the Mechanical Behavior of Materials, 2002
The objective of this research is to fit normal and lognormal distributions to fatigue crack growth rate (da/dN) data and present the data in terms of cumulative frequency distribution (f (x)) and a variant of da/dN and mode I stress intensity factor range (ΔΚ), z. The probability density functions (F(da/dN)) were also plotted for the data.

Modelling fatigue crack growth in shape memory alloys [PDF]

open access: yesFatigue & Fracture of Engineering Materials & Structures, 2022
AbstractWe present a phase field‐based framework for modelling fatigue damage in Shape Memory Alloys (SMAs). The model combines, for the first time: (i) a generalized phase field description of fracture, incorporating multiple phase field formulations, (ii) a constitutive model for SMAs, based on a Drucker–Prager form of the transformation surface, and

A Comparison of Two Methods Modeling High-Temperature Fatigue Crack Initiation in Ferrite–Pearlite Steel

open access: yesCrystals, 2022
High-temperature fatigue tests are carried out to investigate the fatigue crack initiation behavior of ferrite–pearlite steel. Two approaches to modeling fatigue crack initiation under high temperatures in ferrite–pearlite steel are developed and ...

The effect of weld residual stresses and their re-distribution with crack growth during fatigue under constant amplitude loading [PDF]

open access: yes, 2010
In this work the evolution of the residual stresses in a MIG-welded 2024-T3 aluminium alloy M(T) specimen during in situ fatigue crack growth at constant load amplitude has been measured with neutron diffraction.

Dislocation Modelling of Fatigue Cracks: An Overview

open access: yesMATERIALS TRANSACTIONS, 2001
The intrinsic threshold behavior of fatigue cracks and the disappearance of any cyclic plastic deformation below a threshold value can be understood by taking into account the discreteness of plasticity with recourse to discrete dislocation models. The aim of this paper is to document the progress in the discrete dislocation modelling within the past ...

Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]

open access: yes, 2010
In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

A Crack Propagation Method for Pipelines with Interacting Corrosion and Crack Defects

open access: yesSensors, 2022
Corrosion and crack defects often exist at the same time in pipelines. The interaction impact between these defects could potentially affect the growth of the fatigue crack.
