Second order element in composite modeling


Updated by Altair Forum User
Hey Guys!
I've just wondering, it is useful to apply second order element for composite in Hypermesh using Optistruct as a solver? I think the composite theories use pretty much linear approximation between layers that's why I'm asking this 'silly' question.
Thanks for answers in advance!
Have a nice day,
Imre
ps.: if you have any good tutorial, books etc. for composite modeling I would be grateful if you can share with me!
