Modeling of Residual Stresses [PDF]

, 2012
In many industries, nickel-base alloys represent an important segment of structural materials. Critical components made of these alloys are relied upon to function satisfactorily in corrosive services. The demand for safe, reliable and cost-effective performance requires that these nickel-base alloys provide the anticipated corrosion resistance ...

The effect of initial stress induced during the steel manufacturing process on the welding residual stress in multi-pass butt welding

International Journal of Naval Architecture and Ocean Engineering, 2018
A residual stress generated in the steel structure is broadly categorized into initial residual stress during manufacturing steel material, welding residual stress caused by welding, and heat treatment residual stress by heat treatment.

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

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
