Modifying Material Physical Properties

This task shows you how to modify physical properties of a material belonging to a .CATPart or a .CATProduct document or a user material contained in the Material set of a .CATAnalysis document.

Open the sample51.CATAnalysis document from the sample directory.

  1. Right-click a material in the specification tree and select the Property contextual menu or double-click a user material under the Material set.

    In this particular example, right-click the Iron material under the Part1-Geometrical Set.1-Extrude.1 object in the specification tree and select the Properties contextual menu.

    The Properties dialog box appears.
    For more details about the Properties dialog box, refer to the Real Time Rendering User's Guide.

  2. Select the Analysis tab in the Properties dialog box.

    • Material: lets you change the material type.
    • Structural Properties: lets you modify the physical parameters associated a material type.
      The following components lets you define the mechanical behavior of the selected material.

    The Structural Properties parameters depend on the selected Material option:

    • Isotropic material:

      An isotropic material is valid only if the following condition is satisfied:

      where is the Poisson Ratio.

    • Orthotropic material 2D:

      An orthotropic 2D material is valid only if the following conditions are satisfied:

      and

      where:

      • is the Poisson Ratio in XY Plane

      • is the Longitudinal Young Modulus

      • is the Transverse Young Modulus.

      To know more about the material characteristics, refer to Failure Criteria.

    • Fiber material:

      A fiber material is valid only if the following condition is satisfied:

      where:

      • is the Poisson Ratio in XY Plane

      • is the Longitudinal Young Modulus

      • is the Transverse Young Modulus.

      To know more about the material characteristics, refer to Failure Criteria.

    • Honey comb material:

    • Orthotropic material 3D:

      An orthotropic 3D material is valid only if the following conditions are satisfied:

      where:

      • is the Poisson Ratio in XY Plane

      • is the Poisson Ratio in XZ Plane

      • is the Poisson Ratio in YZ Plane

      • is the Longitudinal Young Modulus

      • is the Transverse Young Modulus

      • is the Normal Young Modulus

      To know more about the material characteristics, refer to Failure Criteria.

    • Anisotropic material:

      This option is not supported by the ELFINI solver.
      If you select this option and launch a computation process, a warning message appears.

  3. Select the desired Material option in the Properties dialog box.

  4. Enter the desired parameters in the Properties dialog box.

  5. Click OK in the Properties dialog box.
