ANSYS: Layering & Wood modelling

[kenny0987]

Hi,

I'm working on a project where I'm performing a structural analysis on a skateboard deck. It'll probably be a composite, i haven't decided just yet.

My plan is to create a model of 1 layer of the deck (the deck isn't solid, its multiple layers glued together), then sandwich them together. I've run into a few problems thus far. First off, assuming I'll simply repeatedly add the same model multiple times, how would i actually put together the layers? Do i have to add contact elements to each surface, each time? Seems rather tedious..
And another thing, how would I define the material properties of the model as wood, Canadian Maple to be exact? Ive had a look at the available options on Workbench, but I don't see any types of wood anywhere, am i missing something?

Any help is greatly appreciated.

Thanks.

I haven't done composite modeling, but I think you'll want to have a look at SOLID185 Layered Structural Solid Elements, Keyopt(3)=1. I believe that layered elements are appropriate for modeling orthotropic materials such as woods or composites.

Depending on what you're after, layered shell elements may also do the trick.

Thanks for the input.
