Residual stress. Part 1 – Measurement techniques
TLDR
In this paper, the effect of residual stresses on fatigue lifetimes and structural integrity are first summarised, followed by the definition and measurement of residual stress, which are characterised according to the characteristic length scale over which they self-equilibrate.Abstract:
Residual stress is that which remains in a body that is stationary and at equilibrium with its surroundings. It can be very detrimental to the performance of a material or the life of a component. Alternatively, beneficial residual stresses can be introduced deliberately. Residual stresses are more difficult to predict than the in-service stresses on which they superimpose. For this reason, it is important to have reliable methods for the measurement of these stresses and to understand the level of information they can provide. In this paper, which is the first part of a two part overview, the effect of residual stresses on fatigue lifetimes and structural integrity are first summarised, followed by the definition and measurement of residual stresses. Different types of stress are characterised according to the characteristic length scale over which they self-equilibrate. By comparing this length to the gauge volume of each technique, the capability of a range of techniques is assessed. In the sec...read more

Residual stress measurement in a repair welded header in the as-welded condition and after advanced post weld treatment
TL;DR: In this article, the residual stresses in a type 316H stainless steel steam header were measured using the deep hole drilling (DHD) technique to characterise the through thickness residual stress distribution in a circumferentially repaired weld in the as-welded condition and after an advanced post weld treatment (APWT) had been applied.

Residual stress induced tension-compression asymmetry of gradient nanograined copper
TL;DR: The residual stress significantly influences the cyclic stress response of the hierarchical nanostructured materials as discussed by the authors, and an obvious tension-compression asymmetry with minimum stress in compression lar...

Residual stress. Part 2 – Nature and origins
TL;DR: In this paper, the authors examine the nature and origins of residual stresses across a range of scales, from the long range residual stress fields in engineering components and welded structures, through the interphase stresses present in composites and coatings, to the microscale interactions of phase transformations with local stresses.
