Experimental and numerical investigation of residual stresses in proximity girth welds
Bhardwaj, Sachin; Ås, Sigmund Kyrre; RATNAYAKE MUDIYANSELAGE, Chandima (Peer reviewed; Journal article, 2023)International fabrication codes and standards provide minimum distance criteria for proximity welds, although rigorous justification is lacking. These distances are either based on practical experience or mutual agreement ... -
Experimental investigation of residual stress distribution on girth welds fabricated at proximity using neutron diffraction technique
Bhardwaj, Sachin; RATNAYAKE MUDIYANSELAGE, Chandima; Polatidis, Efthymios; Capek, Jan (Peer reviewed; Journal article, 2022)Maintaining minimum distance between repair and existing welds often becomes impractical due to the presence of compact layouts, original welds of branches, nozzles, etc. on offshore structural elements, pipelines, and ... -
Finite Element Analysis of Steel Plates with Rectangular Openings Subjected to Axial Stress
Al-Yacouby, Ahmad Mahamad; Arwie Amri, Mazli; Liew, M. S.; RATNAYAKE MUDIYANSELAGE, Chandima; Samarakoon, Mudiyansele Samindi Manjula K (Peer reviewed; Journal article, 2022)Steel plates with openings are among the important ship structural components used in the ship’s hull to withstand the hydrostatic forces of the ocean, which cause sagging and hogging moments at the ship’s bottom. The ... -
