Which shell modelisation are you choosing ?
I am having a philosophical questionning on these situation. I am working in steel structure qualification, and I often perofrm 2D shell analysis.
However, I am always having a question when modeling two plates on top of each others, welded arround the top on (on the highlighted edges of the first image).
Which one of the following modelisation represents the best the real physics (depending on the exterior interaction) :
- mid shell + MPCs arround the edges
- top shell + bottom shell with the nodes on the shared edges fused
I am really interested in your vision on this.I am having a philosophical questionning on these situation. I am working in steel structure qualification, and I often perofrm 2D shell analysis.
