Title: High performance computation of residual stress and distortion in laser welded 301L stainless sheets

Abstract

Transient thermo-mechanical simulation of stainless plate laser welding process was performed by a highly efficient and accurate approach-hybrid iterative substructure and adaptive mesh method. Especially, residual stress prediction was enhanced by considering various heat effects in the numerical model. The influence of laser welding heat input on residual stress and welding distortion of stainless thin sheets were investigated by experiment and simulation. X-ray diffraction (XRD) and contour method were used to measure the surficial and internal residual stress respectively. Effect of strain hardening, annealing and melting on residual stress prediction was clarified through a parametric study. It was shown that these heat effects must be taken into account for accurate prediction of residual stresses in laser welded stainless sheets. Reasonable agreement among residual stresses by numerical method, XRD and contour method was obtained. Buckling type welding distortion was also well reproduced by the developed thermo-mechanical FEM.

Progressive collapse analysis of stiffened panel structure with consideration of actual welding distortion and residual stresses

Conference Huang, Hui ; Murakawa, Hidekazu ; Ma, Ninshu ; ...

To date, inclusion of welding distortion and residual stresses in determining the strength of marine structures is based on empirical formulations due to welding complexity. In this study, a more feasible numerical model was developed from the perspective of inherent strain theory. The accuracy of this simplified numerical model was confirmed by transient thermo-elastic–plastic finite element analysis using a novel dynamic mesh refining and iterative substructure method which is 50 times faster than conventional finite element method. Welding distortion by the two numerical approaches was validated with experimental measurement. The collapse analyses indicated that the inherent strain model predicted amore »« less

Journal Article Wu, Xin - Journal of Nuclear Materials

Chloride-induced stress corrosion cracking (CISCC) in the weldments of austenitic stainless steel canisters is one of the primary safety concerns during the dry storage of used nuclear fuel at Independent Spent Fuel Storage Installations in coastal areas. In order to evaluate the CISCC behavior in the canister, a 3D sequentially coupled thermo-mechanical finite element model was built to simulate the residual stresses induced by two intersecting longitudinal and circumferential multi-pass welds in austenitic stainless steel mockup canister. Weld-induced residual stresses from simulation were in good agreement with the experimental measurement results by deep-hole drilling and contour methods. Through-wall high tensilemore »« less

Distortion and residual stress generation in laser beam welding calculated by the finite element method

Conference Hillebrand, A ; Decker, I ; Wolfahrt, H

The laser beam opens new industrially relevant welding applications under different aspects: precision welding, welding of complex structures, joining of conventionally nonweldable materials, high speed welding, etc. On the other hand, the resulting weld quality depends on a large number of process parameters which have to be optimized for each application. Since trial-and-error developments are often very time and cost intensive, powerful techniques of numerical process simulations are necessary, especially in this field. The physically very complicated mechanism of beam absorption within the keyhole is modeled by a special version of load steps which are capable of simulating the continuousmore »« less
An improved prediction of residual stresses and distortion in additive manufacturing

Journal Article Mukherjee, T. ; Zhang, W. ; DebRoy, T. - Computational Materials Science

In laser assisted additive manufacturing (AM) an accurate estimation of residual stresses and distortion is necessary to achieve dimensional accuracy and prevent premature fatigue failure, delamination and buckling of components. Since many process variables affect AM, experimental measurements of residual stresses and distortion are time consuming and expensive. Numerical thermo-mechanical models can be used for their estimation, but the quality of calculations depends critically on the accurate transient temperature field which affects both the residual stresses and distortion. Here in this study, a well-tested, three-dimensional, transient heat transfer and fluid flow model is used to accurately calculate transient temperature fieldmore »« less

Effects of residual stresses and distortion on the nickel 200 and stainless steel 304 weldments

Technical Report Sunwoo, A J ; Mahin, K W

Autogenous bead-on-plate welds made on nickel 200 and stainless steel 304 (SST) using the gas tungsen arc welding process. The transient thermal repsonses and displacement were monitored during welding using spot-welded thermocouples and linear voltage displacement transducers (LVDT).Variations in the parameters included plate thickness, current, heat input, travel speed, and restraint conditions. Electrode geometry and shielding gas were kept constant. Residual stresses were measured after welding using the blind-hole drilling technique. Comparison were then made between the fusion zone geometry as determined metallographically, and the resultant residual stress and distortion distributions. Results of the thermal responses indicated that the twomore »« less
