Hello Every one

We are finding difficult in validating NASTRAN CQUARD element meshed as box and estimating EI values for Isotropic materials, still Hypersizer we are finding different answer , any guidance pls

Hello,

Can you provide a little more information? Are you using the FEM viewer's "section cut" capability to compute EI using HyperSizer? How different are the values you're computing by hand compared to those from HyperSizer?

Things to keep in mind: tension vs. compression vs. average modulus, reference plane / shell or property offsets.
