is it possible bi-directional composite laminates analysis in ansys???

Submitted by murugesan_kpm on

hi  this murugesan.....i am doing project on composite materials......i have one big doubt in composite analysis...i am using 0+90 net like fiber composites.....i want to analysis laminates of 0+90 orientation of 5mm thicknes and 8 plies.....these orientation are bi-directional.......i found in ansys, we can apply the orientation of uni-directional ply only.........my question is, if anyss can analyss the bi-directional laminates?....how can we give bi-directional orientation.....if ansys did nt perform means, suggest any useful software for performing bi-directional laminates analysis..........kindly inform me through mail also....    murugesan_kpm [at] yahoo.com (murugesan_kpm[at]yahoo[dot]com)

thanking you,

Hi,

I personally feel that this can be simulated in ANSYS. Try to get lamina level properties of bi-directional fabric. Main advantage in bi-directional fibers is improved E22 and E33 compared to those in unidirectional (UD) fibers. E22 may also be equal to E11 if  fibers in [0] and [90] direction are equal. Use lamina level properties of bi-directional fibers for assigning layerwise properties as we do in case of UD fibers. I think it should work.

Best regards,
