A gasket material model is used to analyze structural components that have a sealing component between them. For additional information on the gasket model, see Gasket in the Material Reference. The gasket is defined by a compression load closure curve, unloading data (linear or nonlinear), and optionally transverse shear and the maximum tension stress. The gasket can additionally be defined at different temperature values by adding an additional Data Set, found in the Gasket-Additional Data category of the Toolbox pane for each temperature.

The compression load closure curve defines the pressure in the material at given closure values. To enter this data, select the Compression item and enter the data in the Table pane.

The unloading data can be entered as linear or nonlinear data. To add unloading data, choose Linear Unloading or Nonlinear Unloading, found in the Gasket-Additional Data category of the Toolbox pane. When choosing linear unloading multiple curves are entered into each row of the table in the Table pane. If nonlinear unloading is chosen each individual unloading curve is added from the Toolbox and then the data is added in the Table pane.

To optionally define the maximum tension stress, add Gasket Parameters, found in the Gasket-Additional Data category of the Toolbox pane.

To optionally define the transverse shear or transverse shear and membrane stiffness, add Transverse Shear or Transverse Shear and Membrane Stiffness form the Gasket-Additional Data category of the Toolbox pane.
