Thanks for the links, George.

I haven't delved into it yet, but I think the toughest part of the problem will involve how to model a non-homogeneous material. How would you model epoxy, for instance, if by itself it looks like swiss cheese when the glass is subtracted out? Do I model it as separate destinct layers of wood, glass, and epoxy? I'll have to search for info on lay-ups and hope I can find data for lay-ups similar to what we use. If it's not available, the model may not be worthwhile. The whole is greater than the sum of its parts.

: The failure loads of cloth/epoxy composites are available at the link below.
: Since design loads are unknown, the best that can be done is to compare
: failure loads of different cloth/epoxy composites.

: For your software, you need items like E, G, and mu for both the glass and
: the epoxy. If your software does not have those numbers for some type of
: composite already, your software will give you the wrong results. A call
: to your epoxy manufacturer will get the numbers for epoxy. You can use the
: numbers in the software for glass.
