shell coat on solid elements
shell coat on solid elements
(OP)
All
I wanted to know why it is recommended to put a shell coat on solid elements?
One possible reason could be that there is a degree of freedom mismatch if the FEA model includes shell-solid connections.
Is there any other reason
I appreciate your help
thanks
regards
James

RE: shell coat on solid elements
Who made the recommendation and in what context?
As you have already indicated there is a compatibility issue when mixing elements of different types which use different shape and displacement functions. It is not good practice to do this and can give rise to errors in result interpretations. I know many analysts do skin solids with shell or membrane elements, but I have yet to see an argument for this practice that holds up under scrutiny.
RE: shell coat on solid elements
Thanks for your reply.
By shell coat I meant membrane elements.
I apologise for the confusion.

Yes, I see your point using it as a quick, crude design iteration, but as you say you don't trust your final analysis being skinned.
I'd still like to know where James has seen this as a "recommendation" !
