Modeling Honeycomb structure in Patran 1

[Pshell90]

Hi guys!!

I'm working with PATRAN and I wanna model a sandwich beam with honeycomb core. but I don't know how to model it in PATRAN? I used COMPOSITE in material and defined facesheet and core !!
I want to know if it is a good way to define a sandwich beam ?
I want to have a flutter analysis at the end !!
Please help me what to do !!
Thank you all in advance .

There are several ways to model sandwich structure. You will not be able to capture the effects of transverse shear stiffness with that approach though. If that does not matter to you, then your approach may be sufficient.

Dear Brian,

Thank you a lot ! but I just for checking, you mean that in this way that I said, the transverse shear modulus does not exit !! I'm sorry, but could you please explain more . I'm a rookie .

Thank you again,Brian.

Dear ZeroExperience,

Could you please tell me how I can model honeycomb structure using MSC.Laminate Modeler ?!

Thank you in advance, my friend.
