The effect of vibratory stress on the welding microstructure and residual stress distribution [PDF]

open access: yes, 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 ...

Determination of Residual Stress Distributions in Autofrettaged Thick Cylinders [PDF]

open access: yes, 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 ...

Modelling of multiple impacts for the prediction of distortions and residual stresses induced by ultrasonic shot peening (USP) [PDF]

open access: yes, 2012
During a manufacturing process, the ultrasonic shot peening (USP) technique can be used as the final surface treatment. The aim of this operation is to introduce surface compressive residual stresses in order to prevent crack propagation advancement ...

The effect of weld residual stresses and their re-distribution with crack growth during fatigue under constant amplitude loading [PDF]

open access: yes, 2010
In this work the evolution of the residual stresses in a MIG-welded 2024-T3 aluminium alloy M(T) specimen during in situ fatigue crack growth at constant load amplitude has been measured with neutron diffraction.

Rapid recovery following short-term acoustic disturbance in two fish species [PDF]

open access: yesRoyal Society Open Science, 2016
Noise from human activities is known to impact organisms in a variety of taxa, but most experimental studies on the behavioural effects of noise have focused on examining responses associated with the period of actual exposure.

Tissue-Specific Recovery Capability of Aroma Biosynthesis in ‘Golden Delicious’ Apple Fruit after Low Oxygen Storage

open access: yesAgronomy, 2022
The impact of low-oxygen (2 kPa) controlled atmosphere storage on the recovery of aroma biosynthesis in ‘Golden Delicious’ (GD) apple tissues during their subsequent shelf life was investigated. The results showed that the highest ester content was found
