Title: Can hypersizer do pcomp/mat8 for a stiffened panel (orthogrid)?
Post by: HyperSizer Moderator on July 11, 2008, 04:43:13 PM

Questions submitted via email from HyperSizer user:

I've been trying to spit out a pcomp/mat8 properties file for a grid stiffened panel and am having trouble.  I still get the pshell/mat2 representation in the PM1 file.  Can hypersizer do pcomp/mat8 for a stiffened panel (orthogrid)?

HyperSizer creates PCOMP/MAT8 properties only for unstiffened or sandwich panel concepts.  In general, the PCOMP/MAT8 approach does not have the generality needed to properly model the stiffness of a stiffened panel, therefore we default back to the PSHELL/MAT2  properties to be sure that we properly represent the stiffness of the panel in the FEA.
