Apply a Hyperelastic Material to the O-Ring

Create a custom rubber material, and apply it to the O-ring.

The custom material behaves according to the Mooney-Rivlin hyperelastic material model.

This task shows you how to:

Create a Custom Rubber Material

Create a new hyperelastic material that inherits the properties of the material assigned to the O-ring in the SOLIDWORKS simulation study, Ready.

  1. From the Setup section of the action bar, click the down arrow next to Material Palette , and select Create Material .
  2. In the Covering Materials section, enter 0 in the Number of Materials field.
  3. In the Core Materials section, confirm that Number of Materials is set to 1.
  4. Optional: In the Core Materials section, enter a descriptive Title (for example, O-ring elastomer material).
  5. In the Core Materials section, expand the Add Domains section, and select Simulation Domain.

    All materials applied to parts in an analysis case must have a simulation domain. A simulation domain consists of material properties and material behaviors.

  6. Click OK.
    The Material Definition: Simulation Domain dialog box appears, and the 3DSearch results list the new material.
    Tip: If the Material Definition: Simulation Domain dialog box is not visible, minimize the 3DSearch window.
  7. Expand Structures > Abaqus Multiphysics > Mechanical > Elasticity, and select Hyperelastic.
    The Hyperelastic dialog box opens.
  8. From the Strain energy potential options, select Mooney-Rivlin.
  9. Enter the following material property values:
    Material PropertyValue
    C10 840 psi
    C01 210 psi
    D1 9.527e−07 _psi

    For 3DEXPERIENCE material property values, an underscore "_" next to a unit indicates division or power of negative one. For example, a value of 10_psi means 10 /psi or 10 psi-1.

    The SOLIDWORKS properties of the Mooney-Rivlin hyperelastic material model map to 3DEXPERIENCE material properties as follows:

    SOLIDWORKS Mooney-Rivlin Material Properties3DEXPERIENCE Mooney-Rivlin Material Properties
    First Material Constant C10
    Second Material Constant C01
    Poisson's Ratio D 1 ⁢ =   3 ( 1 ⁢ − 2 v )   2 ( 1 ⁢ +   v )   ( C 10 ⁢   +   C 01 )
  10. Click OK.
    You created a custom rubber material.

Apply the Material to the O-Ring

  1. In 3DSearch, click the down arrow next to the new material and select Apply.
  2. Select the O-ring in the 3D area.
  3. Click Close Command to close the context toolbar.
