How to create the woven glass fiber in Radioss?

Paphatsorn

I am doing the drop weight test. And the material that I need use is Woven glass fiber. Usually I use ply-based modelling to create composite. But when I create ply, it allows me to define the orientation of each ply in 1 direction, it's not woven glass fiber that we have 2 orientation in each ply.

 

When I search in the tutorial, I only see the same approach that I am doing now, but it does not the thing that I have to do. 

How can I model woven glass fiber in radioss?

This is the model that I need to create.

Thank you in advance.

You can still do it this way, the ply orientation is just defining the base (0) orientation of the ply. Obviously with UD plies, you care what this orientation is 0,90,45 etc as you need to align your material orthotropy correctly. But If your ply material (woven glass fibre) has the same behaviour in both 0/90 then that is fine, it doesn't matter then whether you set those plies as 0 or 90 in that case. (the orthotropy is defined on the material, only the orientation is set on the ply), so for your example, you can define a single material for your woven plies and use 45 for the 45/-45 ones and 0 for the 0/90.

Taking this further, you could even have an isotropic ply made of aluminium for example, the 'ply orientation' would not matter at all then, but it would still ask for one.
