The non-destructive and phase selective determination of residual stresses caused by material processing (such as welding) in polycrystalline samples is usually performed by diffraction methods. In order to obtain information about stress fields at high spatial resolution with conventional methods, for example with micro beam techniques, the sample needs to be scanned in a very time consuming manner. A much faster method is the simultaneous investigation of a larger area using position sensitive diffractometry. This method was used for the analysis of the residual stress distribution in laser beam welded thin (2 mm and 3 mm) magnesium sheets.

This paper presents a destructive procedure for the determination of longitudinal residual stress distribution in a thin layer in the vicinity of the running surface of a rail head and the neighbouring area of rail cross-section. Wheel passages on the track produce plastic deformation in the running surface layer and thereby create a strong compression with a sharp stress gradient in the layer. This longitudinal stress distribution is a very important component of the stress pattern and strongly influences crack propagation in the rail head.

Abstract One of the important factors to be considered in design is the residual stress distribution in the component. The positive or negative effect of these stresses plays an important role in the life of components. The unexpected failure of the components latter determined to be attributed to the residual stress distribution is not uncommon. Often in the design of nuclear reactor coolant system and components, the level of residual and transient thermal stress distribution is an important factor to be considered. Obviously the level of these stresses depend on the fact that if the material is sensitive (material with temperature dependent properties or insensitive. In this paper an infinite hollow cylinder is considered as an example. A theoretical study, which predict the thermoelastoplastic and residual stress distribution is presented. A quasi static and uncoupled thermoelastoplastic analysis based on incremental theory of plasticity is developed and a numerical procedure for successive approximation is presented. The problem is solved for both case of sensitive and insensitive material. The level of residual and thermoelastoplastic stress for both cases are compared and discussed in detail.
