Editing User Isotropic Materials

This task shows you how to edit a user isotropic material with no geometrical support.

For example, this material should be useful for properties that have mesh support.

From the V5R14 release, you cannot create a user isotropic material anymore.
You can only edit a user isotropic material that has been created in the previous releases.

Open the sample48_1.CATAnalysis document from the sample directory.

  1. Double-click the User Isotropic Material object under the Material.1 set in the specification tree to edit it.

    The User Isotropic Material dialog box appears.

    • Name: lets you change the name of the user isotropic material.
    • The following components lets you define the mechanical behavior of the material
      • Young Modulus (in N_m2)
      • Poisson Ratio
      • Density (in kg_m3)
      • Thermal Expansion
      • Yield Strength (in N_m2)

  2. If needed, modify the parameters in the User Isotropic Material dialog box.

  3. Click OK in the User Isotropic Material dialog box.
