FNA analysis with layered non-linear shells
FNA analysis with layered non-linear shells
(OP)
Hello,
Can anyone clarify this statement about the 3 requirements for using FNA.
-Be primarily linear-elastic.
-Have a limited number of predefined nonlinear members.
-Lump nonlinear behavior within link objects.
The model I am using has layered non-linear shells that are defined by non-linear material properties. There are also non-linear links. Does "a limited number of predefined nonlinear members" include nonlinear shells?Can I use FNA?
Thank you,
Neil

I saw a video of a performance based design seminar conducted by CSI in which their company President said that an upcoming version will allow FNA to consider material NL behavior. Not sure when that new version is supposed to be released.
