Welding Residual Stress Effect in Fracture Toughness
Journal of Nanoscience and Nanotechnology, 2019The thickness of steel plates used for large structures has been increasing with the rapid increase in the size of welding structures. The growing capacity of large-scale ships, such as container ships, has led to an increase in the thickness and strength of steel plates for shipbuilding.

Welding residual stresses have been always seen as a threat to the integrity of structures and components during service loadings. However residual stresses could partially or even totally relax under thermal or mechanical external loads if the sum of ...

Residual Stress Prediction for the Inertia Welding Process
Journal of Neutron Research, 2004Predictions of residual stresses in inertia friction welded Ni-base superalloys have been carried out using a commercial finite element code (DEFORM) combined with an energy balance approach and a 2D axisymmetric formulation. A coupled thermal and mechanical finite element model has been created.

The Variability in Weld Residual Stress
Volume 6B: Materials and Fabrication, 2019Abstract Residual stresses resulting from welds are a key consideration in the design and assessment of piping and pressure vessels. As welding is a variable process, the resulting variability in weld residual stress should be accounted for in design and assessment.

Redistribution of the residual welding stresses
Marine Systems & Ocean Technology, 2013This paper presents an experimental study of the residual welding stresses for butt-jointed steel plates. The stresses were monitored over two weeks after the removal of the welding constraints. The measurements were performed at the deposited metal, the heat-affected zone, the base metal close to the weld joint and along the plate using the X-ray ...
