Establishing inherent deformation database for Q355 steel T-joints in stiffened panels by numerical approach and artificial neural network

The typical welding joints in stiffened panels are generally subjected to different structural restraint conditions, and the welding processes applied to individual joints may also vary to some extent. Consequently, inherent deformations may differ among joints within a given str...

Numerical investigation of residual stress and welding deformation in S700MC/DP1180 dissimilar-metal butt-welded joint

This study proposed material models for the S700MC/DP1180 dissimilar-metal butt-welded joint, which accounts for solid-state phase transformation and tempering softening. Based on the models, a numerical approach was employed to calculate the welding-induced stress and deformatio...
