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 ...

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 ...

Analysis and prediction of residual stresses based on cutting temperature and cutting force in rough turning of Ti–6Al–4V

Heliyon, 2022
Turning is a typical machining process, which is widely used in the manufacturing process of parts. The residual stress introduced by turning has a significant influence on the mechanical properties, fatigue performance, and service safety, and is one of

Correlations between Microstructure and Residual Stress of Nanoscale Depth Profiles for TSV-Cu/TiW/SiO2/Si Interfaces after Different Thermal Loading

Materials, 2023
In this paper, the residual stresses with a nanoscale depth resolution at TSV-Cu/TiW/SiO2/Si interfaces under different thermal loadings are characterized using the ion-beam layer removal (ILR) method.

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

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
