How to set orientation for filament winding composites using type 11 card with mat 25
Plz brief on the use of P11_SH_SANDW card.
Hi Jones,
Use PHIi in type prop/type11 card to define orientation.
before that you need to define a global vector which define the material direction.
Many Thanks Prakash.
Could you please briefly explain ur answer
I'm working on Zone based multi directional and bi-directional plies,in that case how many co-ordinate systems had to be created and How??
or send help link regarding that if poss.
Regards,
Jones
You can find more information about TYPE 11 property in RADIOSS starter help.
Please refer to help to learn more on this.
In your case, you need one property for one zone.

can anyone tell me how to define bidirectional ply orientation in optistruct and block 110
thanks
Hi Jessica,
BiDirectional ply definition is based on Material property. If E11 and E22 are same in MAT8 card then the ply is assumed as bi-directional.
If the case is reverse, that is E11>> E22 then it is a uni-directional ply.
HI Prakash, I got a doubt reg the same, I have underwent many analysis on Mat 8 card with UD composites....As u are telling that if E11 & E22 are same,Software will consider it as bidirectional. How to assume the difference between UD and BD? will the same be reflected in the result?
Jones,
You will see the difference in the results.
Consider a UD.. The strength will be much greater in the major direction when compared to the minor direction (or less stiffer)
in the same way, BD will possess similar or almost near strength in both major and minor directions.
