Evaluation of the intrinsic crack growth rates of weld joints [PDF]

, 2011
A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...

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

, 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.

Dynamic Shear Deformation in Zinc Crystals [PDF]

, 1962
The initial stages of yielding in single crystals of zinc have been investigated at temperatures of -292°F (-180°C), -93°F (-70°C) and +75°F (24°C), by means of rapidly applied constant stress pulses to produce slip along the basal planes of these ...
