hello there,

 

I am presently working on automotive suspension modelling using composites. I need to model Bi-directional(WOVEN_FABRIC) plies using hypermesh. Did not find much setting up procedures w.r.t woven fabric.How to proceed using ply entity options??. what is an equivalent way of modelling woven fabric in hypermesh??.

 

help me with your valuable suggestions.....

 

Thanks in advance

 

Thanks and Regards,

Mohamed Sharieff.

    Hi Mohamed,

     

    Please let us know which solver are you using. is it OptiStruct or RADIOSS?

     

    In RADIOSS you may consider using /MAT/LAW58 for modelling anisotropic fabric.

     

    If OptiStruct, you may consider using 1D elements to model woven material.

    Hi @durukanbdilek

     

    You can use a single ply with E1~= E2 which behaves like a cloth.

    Hi,

     

    You can use MAT8 card in OptiStruct solver.

    @durukanbdilek use PCOMP.. property card

    and orient your mesh (menu Tools>Orientation Review)

    Hi @durukanbdilek

     

    I am not sure from which modelling tool it is. So I can't comment about that.
