I'm performing a buckling analysis of a stiffened aluminium panel. The panel and flatbar stiffener(2) is created as one 3D shell extrusion. The T-stiffener (1) is another 3D shell extrusion.
How do I connect the two parts? I have tried the "create interaction"-button, but have no clue how to do it. I guess the load transfer might not work as intended if I connect them wrongly as I'm not very used to shell elements either. Can I connect the shell edge of the T directly to the face of the panel? I'm using Abaqus btw.
The partitions of the panel and T-profile are there to simulate HAZ-effects. Are there other options to specify heat affected zones and potentially residual stresses?
All help is highly appreciated!
