Effect of homogenization annealing on internal residual stress distribution and texture in ME21 magnesium alloy extruded plates

open access: yesJournal of Magnesium and Alloys, 2019
The distribution of residual stresses through thickness of 5 mm-thick ME21 magnesium alloy extruded plates was analyzed non-destructively using short-wavelength X-ray diffraction (SWXRD), and the effect of homogenization annealing before extrusion on the

Nonlinear parallel momentum transport in strong turbulence

open access: yes, 2015
Most existing theoretical studies of momentum transport focus on calculating the Reynolds stress based on quasilinear theory, without considering the \emph{nonlinear} momentum flux-$$.

Evolution of Residual Stress Based on Curvature Coupling in Multi-Roll Levelling

open access: yesApplied Sciences, 2019
Residual stress is the main cause of flatness defects in sheet metal and the basic method to improve the shape quality of the sheet is to reduce and eliminate the residual stress by multi-roll levelling.

Mean stress correction in fatigue design under consideration of welding residual stress

open access: yesWelding in the World, 2020
The fatigue strength of welded steels is affected by the applied load mean stress and the residual stress in the vicinity of the weld. The mean stress correction in fatigue design concepts used for welded structures commonly distinguishes between three ...

Effect of Transverse Restraint on Welding Residual Stress in V-Groove Butt Welding

open access: yesMetals, 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.
