im doin my final yr proj on composite shell......actually my structure involve a single layerd and a bidirectional fiber orientation...

But i felt really tough in solving usin ANSYS..i started my proceedings with some approximations ie) i hav used modelling->layup option with an assumption of 0.5 mm thick layer of 0 deg orientation....nd remaining 0.5mm thick layer of 90 deg orientation...

but my stucture involves an interwoven fabric structure....so im not sure whether im moving rite.....so pls give me ur suggestions
