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

Liljedahl, C. D. M.; Zanellato, O.; Fitzpatrick, M. E.; Lin, J.; Edwards, L. (Elsevier, 2010-04)

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. The plastic ...
The Effects of Residual Stress and HAZ on Fatigue Crack Growth in MIG Welded 2024 and 7150 Aluminium

Lin, J.; Ganguly, Supriyo; Edwards, L.; Irving, Phil E. (2003-01-01)

The effect of weld residual stress, and hardness profile on fatigue crack propagation in MIG welded 2024 and 7150 aluminium joints was studied. Residual stress fields in the weld were measured using neutron diffraction. ...
An Integrated Approach to the Determination and Consequences of Residual Stress on the Fatigue Performance of Welded Aircraft Structures.

Edwards, L.; Fitzpatrick, M. E.; Irving, Phil E.; Sinclair, I.; Zhang, X.; Yapp, David (2006-02-01)

Although residual stress in welded structures and components has long been known to have an effect on their fatigue performance, access to reliable, spatially accurate residual stress field data has been limited. Recent ...
Problems in using a comb sample as a stress-free reference for the determination of welding residual stress by diffraction

Ganguly, Supriyo; Edwards, L.; Fitzpatrick, M. E. (Elsevier Science B.V., Amsterdam., 2010-12-31)

Precise measurement of a stress-free reference lattice parameter is vital in the determination of residual stress by diffraction techniques using θ/2θ-based analyses. For the evaluation of the residual strain profile in ...
Weld residual stress effects on fatigue crack growth behaviour of aluminium alloy 2024-T351

Liljedahl, C. D. M.; Brouard, J.; Zanellato, O.; Lin, J.; Tan, M. L.; Ganguly, Supriyo; Irving, Phil E.; Fitzpatrick, M. E.; Zhang, X.; Edwards, L. (Elsevier Science B.V., Amsterdam., 2009-06-30)

The interaction between residual stress and fatigue crack growth rate has been investigated in middle tension and compact tension specimens machined from a variable polarity plasma arc welded aluminium alloy 2024-T351 ...
