Thats a good start, Im sure someone so smart could be a little more specific!!

Presumabley if you have FE software you'll have access to the manuals? If your code allows for composite shell elements (has a composite shell property input option) then input is a matter of describing the layers, their thickness and referring them to material definitions. You of course need sensible material models for each. That's the easy part. Interpretting the results is a question of checking for failure both within a layer and in the shear between the layers and using failure criteria appropriate to both the material and it's position within the whole.

If you have to, you can define the composite using multiple shells on the same grid points so long as you can offset their position in the 'thro-thickness' direction with respect to the nodes/grids.

Thank you
