Use of a new methodology for prediction of weld distortion and residual stresses using FE simulation applied to ITER vacuum vessel manufacture

Thermo-hydraulic analysis of the generic equatorial port plug design

“…These properties were obtained from [6,7] for the SS 316LN IG (Table 1). Table 2 shows cooling temperature dependent properties.…”

A study of the influence of electron beam welding sequences on the ITER vacuum vessel prototype VATS

“…Field coupling due to plastic heat generation is neglected in the analysis. Material behaviour model is summarized in [20][21][22].…”

“…The welding simulation methodology was developed and successfully used in [20]. The simulation includes the weld passes and the cooling periods according to the specifications of the electron beam vacuum chamber.…”

Determination through the distortions analysis of the best welding sequence in longitudinal welds VATS electron beam welding FE simulation

“…Field coupling due to plastic heat generation is neglected in the analysis. Material behaviour model is summarized in [10,11]. Fig.…”

“…In previous papers [10][11], the finite element simulation was used to validate the model by means of distortions and residual tensions. In this case the simulation was used to manufacture the VATS with an improved welding sequence based on the indicated tolerances.…”
