Assigning Material Properties

Assign Steel AISI 304 from the material library to the groove and the top plate components.

To define the material of the O-ring:

  1. In the Simulation study tree, right-click the O-ring icon and select Apply/Edit Material.
  2. In the Material dialog box, right-click the Custom Materials folder and select New Category.
  3. Right-click the newly defined category and select New Material.
  4. In the Material properties box, do the following:
    1. Set Model Type to Hyperelastic - Mooney Rivlin.
    2. Set Units to English (IPS).
    3. Type Rubber1 in the Name box.
  5. In the material properties table, enter the following material properties:
    1. For Poisson's Ratio, type 0.4995.
    2. For First Material Constant, type 840.
    3. For Second Material Constant, type 210.
    4. Type a value for Mass Density, say, 0.04.
      The value of mass density does not affect the results for this problem but it is a required physical property.
  6. Click Apply.
