Through-thickness distributions of the welding residual stresses were studied in the range of 50100 mm thick plates by using finite-element modeling (FEM) and neutron diffraction measurements. In order to simulate the residual stresses through the thickness of the thick weld joints, this paper proposes a two-dimensional generalized plane strain (GPS) finite-element model coupled with the mixed work
Finite Element Simulation of Thermal Residual Stresses in Jan 20, 2005 · Finite element analysis was used to estimate thermal residual stresses developed in silicon nitride bodies bonded by metallic interlayers. Stresses were calculated for various characteristic metals, namely, Ni, Al, and Si, assuming elastic and elasticplastic behavior.
Intrinsic Strain Modeling and Residual Stress Analysis for In general, the residual stress/strain of multi-layers thin film is combined of intrinsic and thermal stresses, the thermal induced mechanical stress can be obtained using FEA but intrinsic stress
Jan 04, 2020 · In this investigation, a T-joint numerical welding simulation of thick steel plates is performed to estimate transient temperature distributions, residual stress field and model deflections. A sequential simulation method is applied in the numerical simulation, where the thermal analysis is done by using the EBD technique to simulate the weld wire melting and metal filler addition while the
Numerical simulation on residual stresses of stainless The major concern in the high tech industries like oil and petroleum industries, automobiles, aeronautical, and nuclear power plants is the control of the defects like distortion in the welded joints and residual stresses occur due to arc welding on the circumferential joints of the thin pipes. Three-dimensional non-linear thermal and thermomechanical numerical simulations are conducted for the tungsten inert gas welding
Simulating Distortion and Residual Stresses in Carburized Apr 04, 2003 · This paper illustrates the application of a new multiphase material model for simulating distortion and residual stresses in carburized and quenched gear steels. Simulation is focused on thin, metallic strips that are heat treated to introduce a through-thickness carbon gradient.

X-Ray Diffraction Technique for Residual Stress
AbstractIntroductionExperimental DetailsResults and DiscussionConclusionsData AvailabilityAcknowledgmentsIn the present work, residual stresses in nickel-based (Ni 625) superalloy weld metal of a 9%Ni steel-welded joint were measured by X-ray diffraction (XRD). This technique presents some difficulties in performing measurements in coarse and preferentially oriented weld metal microstructures. It is proposed a preliminary surface treatment by rotating steel wire brushing to perform the stress analysis through XRD technique possible for this kind of material. Stress measurements with proposed XRD technique showeIdentification of process-induced residual stress/strain Apr 10, 2019 · Abaqus-based simulation using these properties was then performed to calculate stress/strain distribution in thick laminates. The simulated strain agreed well with the measured value and it was confirmed that the residual stress developed in a relatively low temperature range.Residual stress simulation in welded sections of P91 pipes Aug 30, 2005 · The peak compressive stresses, if there are any, occur nearer to the outside surface of the pipe in the thin walls and nearer to the inside surface of the pipe in the thick walls. This proclivity of the modelled residual stresses is also demonstrated by another type of steel, stainless steel, for the same geometric arrangement of the welded pipes, which has been reported by Yaghi et al.  .
