*VOLUMETRIC TEST DATA
See “Using the DEPENDENCIES parameter to define fieldvariable dependence” in “Material data
definition,” Section 16.1.2of the ABAQUS Analysis User ’sManual, for more information.
Data lines to specify volumetrictest data for hyperelasticity other than the Marlow model:
First line:
1. Pressure, p.
2. Volume ratio, J(current volume/original volume).
Repeat this data line as often as necessary.
Data lines to specify volumetric test data forthe Marlow model:
First line:
1. Pressure, p.
2. Volume ratio, J.
3. Temperature, .
4. Firstfield variable.
5. Second field variable.
6. Etc.,uptofivefieldvariables.
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greaterthan five):
1. Sixthfield variable.
2. Etc.,up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the test data as a function of temperature
and other predefined field variables. The volume ratios must be given in descending order.

There are no parameters associated with this option.
Data lines to specify volumetric test data fora hyperfoam:
First line:
1. Pressure, p.
2. Volume ratio, J(current volume/original volume).
Repeat this data line as often as necessary.
