Numerical calculation of residual stresses and deflections in a t-joint carbon steel welded structure using temperature-independent material properties

This study investigates the influence of temperature-independent thermal and mechanical material properties on residual stresses and deformations in a T-joint welded structure made of carbon steel. A T-joint model with two single pass welds was numerically analyzed using the finite element method. It was concluded that the model with temperature independent material properties could be suitable for calculating residual stresses, however, it is not suitable for calculating post weld deformations of the welded sample.
