Using anisotropic materials

      Hi, I am looking to correctly create a material with the data shown in the table. The properties are different in the machine direction (MD) and transverse direction (TD). The material is a thin film, i would also like to orientate the properties correctly in the model.


       


       


      Also in thmmodel I am using carbon fibre rods (which support the film) at the top and left edge


      My question: How do ensure the anisotropic material properties are correctly orientated in the models parts?  


      I need the MD to be in say the X direction of the thin film membrane. For the carbon rods I need the anisotropic properties in the correct directions.  I'd be grateful for any advice or guidance, thanks.

      Are you using Ansys Mechanical for this?


      Thanks

      Yes, I using static structural analysis in ansys mechanical.



      Thanks.

      Hi, I only have access to the student portal.

      Please check my signature, it explains how to access the ansys help links.


      Basically you need to use element orientations.

      Hello, 

      I have two questions please;

      1. how can i define a 45° oriented youngs modulus of a material  ? is it possible with the orthotropic model definition ? Since with orthotropic modelling we just have orthogonal axes (90°) --> I have the youngs modulus in longitudinale direction, transverse direction and oblige(45°) direction. I can input the longitudinale direction(x) and transverse direction(y,z) what about the 45° ?

      2. can i assigned 2 material property in ansys which are reference to two different coordinate system? ( exemple i wish to define two local coordinates system with different orientations, then assigne orthotropic properties to each coordinates systems)
