Reply To: Material variables in one direction of coordinate system

Hello!

To model non-homogeneous materials in Ansys Workbench, you'll need to define material properties as a function of your spatial coordinates (in this case, the radius R). Here’s a basic outline of how you can do this:

1. Material Variable: You can use a "tabular data" or create a custom material function that varies with the radius R.

2. Command Snippets: Insert a command snippet in the simulation to define properties like Young’s modulus (E) and shear modulus (G) as a function of R. Use APDL code like:

   apdl

   Copy code

   E = E0 * (1 + alpha * R) MP, EX, 1, E

3. Define Coordinates: Ensure you're working in cylindrical coordinates and link your material properties to the local coordinate system.

4. Engineering Data: You’ll likely need to customize the material in the Engineering Data section, using expressions or formulas.

You can find helpful examples in the Ansys documentation or through APDL code tutorials. Let me know if you need more details!

Good luck!
