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 complex 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.
