Evolution of residual stress at a fatigue crack tip and its influence on crack tip shielding and plasticity

Journal of Materials Research and Technology
The evolution of residual stresses (RS) at a crack tip and associated changes in crack shielding effects during fatigue crack growth (FCG) has a first order effect on the fatigue life of welded joints.
