Defining the membrane behavior of a gasket

You can define the linear elastic behavior of the gasket by providing Young's modulus and Poisson's ratio. These data can be a function of temperature and/or field variables. If you do not specify the linear elastic behavior of the gasket, the gasket has no membrane stiffness. In this case you must ensure that the nodes of the elements are restrained adequately in the directions orthogonal to the thickness direction of the gasket.

  1. From the menu bar in the Edit Material dialog box, select OtherGasketGasket Membrane Elastic.

    (For information on displaying the Edit Material dialog box, see Creating or editing a material.)

  2. Toggle on Use temperature-dependent data to define the data as a function of temperature.

    A column labeled Temp appears in the Data table.

  3. Click the arrows to the right of the Number of field variables field to increase or decrease the number of field variables on which the data depend.

  4. In the Data table, enter Young's modulus and Poisson's ratio data. Include temperature and field variable data if applicable. For detailed information on how to enter data, see Entering tabular data.

  5. Click OK to close the Edit Material dialog box. Alternatively, you can select another material behavior to define from the menus in the Edit Material dialog box (see Browsing and modifying material behaviors, for more information).
