Shell neutral axis offset consideration in NASTRAN

Shell neutral axis offset consideration in NASTRAN

Shell neutral axis offset consideration in NASTRAN

(OP)
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,

kilb

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

Cheers
