4. Closure (deﬁnes the level of preload).

Repeat this data line as often as necessary to deﬁne the effective thickness-direction gasket loss and

storage moduli as functions of frequency and preload.

Data lines to deﬁne effective thickness-direction gasket properties if PRELOAD=UNIAXIAL

is not included:

First line:

1. Real part of . ,where represents the com plex effective thickness

direction dynamic stiffness.

2. Imaginary part of

. ,where represents the complex effective

thickness direction dynamic stiffness.

3. Frequency, f, in cycles per time.

Repeat this data line as often as necessary to deﬁne the normalized effective thickness-direction gasket

loss and storage moduli as functions of frequency.
