*VOLUMETRIC TEST DATA

See “Using the DEPENDENCIES parameter to define field variable dependence” in “Material data
definition,” Section 16.1.2 of the ABAQUS Analysis User’s Manual, for more information.

Data lines to specify volumetric test 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 for the Marlow model:

First line:

1. Pressure, p.

2. Volume ratio, J.

3. Temperature, .

4. First field variable.

5. Second field variable.

6. Etc., up to five field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than five):

1. Sixth field 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.

Hyperfoam material model

*HYPERFOAM

There are no parameters associated with this option.

Data lines to specify volumetric test data for a hyperfoam:

First line:

1. Pressure, p.

2. Volume ratio, J (current volume/original volume).

Repeat this data line as often as necessary.
