Hi,
I am working on a splice analysis, which is not modeled explicitly in the FEM. All I have are a couple of CQUAD elements, which look like continuous skin. I overlapped the geometry on to the FEM in order to identify the location of the splice and only for those elements extracted the running loads from the shells. Now, what is the best way to analyze the rivets (shear, bending, tension etc.) for this kind of modeling?
Given:
1. The running loads in shell elements Nxx, Nyy etc in, lbs/in.
2. The actual fastener pitch p in, in.
3. No. of fasteners n
4. Element lengths le in, in.
5. There is no intent to model the fasteners by one dimensional elements or MPCs
Any suggestions would be greatly appreciated!
Thanks
