residual stresses after welding
residual stresses after welding
(OP)
Hi,
i need to model & compute residual stresses after laser welding of two steel plates,using ABAQUS. To start simple, I'v started off with "coupled temp-disp. analysis" for a statically indeterminate beam, having a uniform surface heat-flux.
I got stresses and temp data too, but now i dont know HOW TO COOL THAT SURFACE to get the residual stresses.
I found in the docs. the (interaction module)film-coefficient, does this job. but where can i find that data? and how can i check the correctness of the residual-stress-output afterwards?
Please help.... i am struggling with this issue since past 2 weeks.
Thanks and regards
