I'm little confused about the fibre orientation in Cross-sectional lamina schema data file in PreVABS, for example in the case of a biaxial[+45/-45] material we'll have mechanical properties for the biaxial coupon. Do I have give this two fibre orientations or I can use 0 deg since the layer'll be in +45/-45. if I have to provide two or even three orientations in case of a triaxial material, How can I provide that in Cross-sectional lamina schema data file.
My opinion is to model it as one layer and use zero degree fiber orientation and mechanical properties you obtained from coupon test; or if you know the mechanical properties of a single uniaxial lamina [0 degree], then you can model your biaxial laminate as two layer.

Thank for your time.

Ning is right.
