Yaser,
try this paper....http://journalsip.astm.org/ctr/PAGES/136.htm
This may not give straight answer to your question. But,I belive,this helps
you knowing more about optimal buckling capacity of composite sections. In
this paper,author used,No. of layers,layer thickness and ply orientations as
design variables for optimal buckling capacity.

You should have asked me this question long time ago because I am writing to
the group almost everyday and I am
getting responses most of time. Regarding who am I and where from, I think
all of us are using this group to
share knowledge and information doen't matter the race or nationality. The
response should not based on such
thing. Also I am attaching a signature with my information in all my
emails.
