Journal ArticleDOI
Determination of the profile of the complete residual stress tensor in a VPPA weld using the multi-axial contour method
TL;DR: In this article, a finite element simulation of the multi-axial contour method was carried out to verify the method numerically, and the results were validated by neutron diffraction measurements.
Journal ArticleDOI
In situ observation of strain and phase transformation in plastically deformed 301 austenitic stainless steel
Yadunandan Das,A. N. Forsey,T.H. Simm,Karen Perkins,Michael E. Fitzpatrick,S. Gungor,Richard J. Moat +6 more
TL;DR: In this article, a strain-induced martensitic transformation is studied by in situ digital image correlation (DIC) in a scanning electron microscope, which enables mapping of transformation strains with high confidence.
Journal ArticleDOI
Residual stress measurement round robin on an electron beam welded joint between austenitic stainless steel 316L(N) and ferritic steel P91

TL;DR: In this paper, a dissimilar metal weld (DMW) between AISI 316L(N) austenitic stainless steel and P91 ferritic-martensitic steel was employed to produce a single bead weld on a plate specimen.
Journal ArticleDOI
Improvement of the Contour Method for Measurement of Near-Surface Residual Stresses from Laser Peening
TL;DR: In this paper, the authors developed a methodology to obtain near-surface residual stresses for laser-peened aluminium alloy samples using the contour method and a new data analysis method based on spline smoothing was applied.
Journal ArticleDOI
Effect of surface texture on the initiation and propagation of small fatigue cracks in a forged 6082 aluminium alloy
S. Gungor,Lyndon Edwards +1 more
TL;DR: In this article, the influence of surface texture on initiation and propagation of small fatigue cracks has been studied in a forged Al-Mg-Si alloy and it has been found that the surface character had little effect on the growth rate although there was about 20% reduction in fatigue life for the as-forged surfaces.
