Gasket material properties overview (Simcenter Samcef)

In Simcenter Samcef, you define the gasket material properties in the Gasket - Strain Material dialog box (Simcenter Samcef Structure).

A gasket material with 5 unloading curves (zero initial closure strain)

To define a gasket material,

• Use the Membrane Material option to specify the isotropic material that defines the material behavior for the membrane (in-plane) direction.

• Use the Yield Pressure (YPRESS) option to specify the initial yield pressure for the gasket. This value must match a point on the specified Loading Curve.

• Use the Tensile Modulus (EPL) option to define the tensile modulus (force per volume mN/mm3).

• Use the Transverse Shear Modulus (GPL) option to define the transverse shear modulus (force per unit area).

• Use the Loading Curve option to specify a field that defines the loading curve of the gasket (pressure vs. closure strain).

• Use the Unloading Curve options to specify fields that define one or more unloading curves for the gasket. You must specify at least one unloading curve. All unloading curves must have the same number of points as the elastic portion of the loading curve (up to the defined initial yield pressure). The first point must be defined at pressure 0.0 and the last point must coincide with a yield point on the loading curve.

• Use the Initial Gap to specify the initial closure strain.
