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. Regards, Uma, Infotech Enterprises Ltd, Hyderabad.

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.
