I am using Abaqus CAE to model a I-Section steel Brige Girder. I want to include the residual stress (due to the welding between flange and web) into my model. I've got the distribution pattern of the residual stress and I know how much stress I should put into each element. since there is only one integration point in each element (I am using Shell element S4R and reduced integration), I am thinking I can assign the stress value to the integration point. Does anybody here have some idea how to perform it in Abaqus CAE? I just can't find the command, or, I can't do it at all? Any relpy are welcome, Thanks!
