Inorder to find out the residual stresses and distortions in butt weld due to thermal loads in steel plates, i have used
shell57 for thermal and shell43 for structural.The material properties used are temperature dependent.
I carried this out in two steps.
The thermal analysis is carried out first.
A moving heat source is used to generate the temperature distribution on the plate.
Following welding the plate is allowed to cool down to room temperature by naturalconvection due to ambient air.The results from the thermal analysis is ok.
