*VISCOELASTIC
4. Closure (defines the level of preload).
Repeat this data line as often as necessary to define the effective thickness-directiongasket loss and
storage moduli as functions of frequency and preload.
Data lines to define effective thickness-directiongasket properties if PRELOAD=UNIAXIAL
is not included:
First line:
1. Realpart of .,where represents the complex effective thickness
direction dynamic stiffness.
2. Imaginarypart of .,where representsthe 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 effectivethickness-direction gasket
loss and storage moduli as functions of frequency.
