Optional parameters
- MODULI
-
This parameter is applicable only when the HYPERFOAM option is used in conjunction with the VISCOELASTIC option.
Set MODULI=INSTANTANEOUS to indicate that the hyperfoam material constants define the instantaneous behavior. This parameter value is not available for frequency domain viscoelasticity in an Abaqus/Standard analysis.
Set MODULI=LONG TERM (default) to indicate that the hyperfoam material constants define the long-term behavior.
- N
-
Set this parameter equal to the order of the strain energy potential. The maximum value is N=6. The default is N=1.
- POISSON
-
Set this parameter equal to the effective Poisson's ratio, , of the material. This parameter is valid only when the TEST DATA INPUT parameter is specified.
If this parameter is included, it is assumed that for all i and that lateral strain test data and volumetric test data are not required. If this parameter is omitted, the are calculated from lateral strain data and/or volumetric test data.
- TEST DATA INPUT
-
Include this parameter if the , the , and the material constants are to be computed by Abaqus from data taken from simple tests on a material specimen. If this parameter is omitted, , , and must be given directly on the data lines.
Data lines to define the elastic properties directly
- First line if N=1
.
.
.
Temperature.
Repeat this data line as often as necessary to define the material constants as a function of temperature.
- First line if N=2
.
.

Temperature.
Repeat this data line as often as necessary to define the material constants as a function of temperature.
- First line if N=3
.

.
.
.
- Second line if N=3
.
Temperature.
Repeat this pair of data lines as often as necessary to define the material constants as a function of temperature.
- Data lines for higher values of N (up to 6)
The data lines for higher values of N follow the same pattern. First, give the and for i from 1 to N. Then, give the N . Finally, give the temperature. Exactly eight data values should be given on each line.
