The effect of vibratory stress on the welding microstructure and residual stress distribution [PDF]
, 2001 Previous studies have suggested that weld microstructure may be modified by the presence of static stresses. In this investigation, vibratory stress was applied to mild steel specimens while they were being welded to observe its effect on the residual ...

Regulation of miR-200c/141 expression by intergenic DNA-looping and transcriptional read-through
Nature Communications, 2016 The miR-141/200 familly of micro RNAs control oxidative stress and impact on ovarian tumorigenesis. Here the authors show that the transcription of miR-200c/141 is regulated through transcriptional read-through of the upstream gene PTPN6, and DNA looping

Determination of Residual Stress Distributions in Autofrettaged Thick Cylinders [PDF]
, 2008 High pressure vessels such as gun barrels are autofrettaged in order to increase their operating pressure and fatigue life. Autofrettage causes plastic expansion of the inner section of the cylinder – setting up residual compressive stresses at the ...

A new approach for the influence of residual stress on fatigue crack propagation
Results in Physics, 2017 Many manufacturing processes can induce residual stresses in produced components. These residual stresses influence the mean stress during cyclic loading. The initial residual stresses induced during manufacturing change during fatigue damage. This paper

Effect of Transverse Restraint on Welding Residual Stress in V-Groove Butt Welding
Metals, 2022 When evaluating the safety of steel structures, welding residual stress is used as the secondary load and if there is any restraint, the yield stress of the base material is used for secondary load, regardless of the size of the restraint.

Characterisation of residual stress state and distortion in welded plates stress engineered by local mechanical tensioning [PDF]
, 2014 Local mechanical tensioning is one of the most efficient and industrially relevant stress engineering techniques to modify weld residual stress field and subsequently reduce buckling distortion. However, application of rolling load and its magnitude need
