Honeycomb Modeling

Honeycomb Modeling

Honeycomb Modeling

(OP)
Could anyone give me a hint on how to conform a honeycomb part to a curved surface or if its even possible in Abaqus?  A explanation on how to conform any part to a curved surface would be a huge help!   

RE: Honeycomb Modeling

You may need to be more specific on what you are trying to do.  Are you trying to deform a honeycomb for an assembly simulation, create geometry for some other loading?  For the first a contact analysis with nonlinear geometry and possibly shells or solids depending on your aspect ratio.  For the second hopefully a shell assumption is valid and you can model as a laminate.  I hope this helps.

Yes, a shell assumption is valid.  Basically what I am trying to accomplish is a head impact simulation.  I would like to take a headform and conform the honeycomb around the head so a drop test could be performed.  Creating the honeycomb on a flat surface is a piece of cake but I'm struggling with a curved surface such as a headform.  Hope that's more specific.

RE: Honeycomb Modeling

So in real life you are taking a honeycomb sheet and conforming it to a rigid steel head then drop testing it to see accelerations for helmet testing?

A shell assumption is probably a big stretch if the honeycomb started off flat.

Another option is to try to create the conformed honeycomb shape in CAD which may be appropriate if you are heating a sheet and then thermoforming it.

I hope this helps.

Yes, that is basically what I'm doing in real life.  What CAD program would you recommend to try to accomplish the conformed honeycomb shape?

RE: Honeycomb Modeling

I believe most commercial CAD packages could make a reasonable approximation of the geometry however it will most likely be tedious.  Personally I would start with SolidWorks but that is because I have the most experience with it.  Start off trying multiple options with greatly simplified geometry.  I hope this helps.

Thanks.  I started off in SolidWorks but I'll continue to work with it to see if I can get what I want.
