Shell neutral axis offset consideration in NASTRAN

[kilbchoi]

Hi!

Is there anyone who knows about the consideration of shell neutral axis offset in NASTRAN ?

Especially when modeling honeycomb panel to the frame(beam) with laminated element, there is a offset for neutral axis with respect to the reference curve.

I saw the dummy element with very weak element property is used to model the offset effect in honeycomb structure in SAMCEF (French FEA code). I'm wondering if I can apply same practice to NASTRAN as well.

Hope to get advice soon.

Thanks,

Yes, that's one good (ish) way of getting the surface stresses.
