Wing rib assembly to wing skin

Hi Wiko,

Hi Prakash,

thank you for the presentation. I tried to realize the sample with a T-beam. The lay-up can be compared to the example, which can be found in the HW-Help (XXXX/Altair/13.0/help/hwsolvers/stack.htm?zoom_highlightsub=ply example 2). I have attached the .fem-file of my model and a short summary of the lay-up.

Actually, I have 4 sublaminates and an interfacelaminate to 'bond' all sublaminates together. I have assigned PCOMPP-property to all mesh-elements. After modeling, I have started a short analysis of the beam but the following error-msg appeared:

*** ERROR # 640 ***
 STACK 5 is incorrectly or ambiguously defined. This could be
 due to disconnected substacks, duplicate interfaces or inconsistent
 interfaces orientations. Please verify the substacks and interfaces
 thoroughly.

Can you give me a feedback with hints to solve this problem? Another question is, does the geometry have to be 'connected together' for modeling a laminate with sublaminates?

Best regards

Wiko

Hi Wiko,

I will have a look at the model and update to you soon.

thanks for sharing the file /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

Hi,

Just interchange the INT3 plies and everything should work fine /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>

Oh, I get it /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'> Thanks! Well does that mean that I have to build up the interface laminate according to the element normal? Like ply8 on the bottom and ply 4 as the second ply?

Yes, exactly /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
