How to simulate a sandwich structure using Hypermesh?

Altair Forum User

Dear

 

Please help me. I want to simulate a sandwich structure using Hyper-Mesh. But I do not know how to connect between FACE SHEET and Honey comb core. After running on LS-DYAN, I receive my result as presented on the figure. How can I correct it? Thanks a lot.

Hi.

How to connect two meshing components?

 And how to share my model?

The thickness of the face sheet is 1.2 mm. So there is a gap of 0.6 mm between face sheet and sandwich core.

There is no gap between face sheet and sandwich core?

Thanks

If you keep the gap, you have to use some technique to stick the central mesh to two shell. Or it's better to extend the surface to link to another.

Dear

Because the shell of the core and the face sheet are simulated as central mesh. Which technique can stick the central mesh  between face sheet and core?

I can not download the file you send.

Thanks
