Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]
, 2011 Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.

Investigation on Residual Stress Loss during Laser Peen Texturing of 316L Stainless Steel
Applied Sciences, 2019 Laser peen texturing (LPT) is a novelty way of surface texturing based on laser shock processing. One of the most important benefits of LPT is that it can not only fabricate surface textures but also induce residual compressive stress for the target ...

Mechanical Tuning of Residual Stress, Memory, and Aging in Soft Glassy Materials [PDF]
Physical Review XGlassy materials rapidly quenched from a liquid to a solid state upon flow cessation or cooling solidify in an out-of-equilibrium configuration, trapping residual stresses and retaining the memory of the processing conditions for very long times, which ...

Influence of girth welding material on thermal and residual stress fields in welded lined pipes
International Journal of Pressure Vessels and Piping, 2022 9 An experimental and numerical investigation on the thermal and mechanical response of a 10 lined pipe (compound pipe) under welding is presented. The welding process consists of a 11 single-pass overlay welding (inner lap-weld) and a two-pass girth ...
