In general, the as-received steel components before welding have usually suffered from
numerous manufacturing processes. There is no doubt that initial residual stresses (IRS) …

A residual stress generated in the steel structure is broadly categorized into initial residual
stress during manufacturing steel material, welding residual stress caused by welding, and …

A lump-pass welding simulation technology was developed for shipbuilding and ship repair
applications based on Battelle and Caterpillar developed VFT™ weld modeling software. To …

Many welding-induced distortion control techniques, weld design optimization, pre-straining,
optimum welding sequence and pre-cambering, were presented and investigated using …

Computational weld modeling is challenging because many of the processes of welding are
highly nonlinear. Material melts and re-solidifies, very high transient thermal gradients are …

Welding distortion and residual stress has remained one of the major challenges in
manufacturing. Extensive experimental efforts have been made throughout the history of …

Virtual fabrication technology (VFT) weld modeling software has been mainly used in thick-
structure welding simulation. Recently both US and European shipyards have shown strong …

ABSTRACT A general numerical procedure was developed to understand buckling
mechanism and be capable of predicting buckling distortion based on a developed rapid …

The USNRC is anticipating updating their leak-before-break (LBB) procedures. One of the
technical areas of concern in the existing procedures is the prediction of the crack-opening …

In this paper, an advanced computational framework is presented for integrated simulation
of hydroforming effects and welding assembly operations. The finite element procedures …
