Second order element in composite modeling

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!

You could run a Composite analysis with the second-order element in OptIStruct.However, the general practice is to use first-order elements.

Hey Rahul!

 

Thanks for the quick answer. I am aware of this ebook and find it pretty useful. I think I will make a few test to compare the two methods.
