This object can be accessed by:

The table data for this object are:
- For a hyperelastic or hyperfoam material model, the table data specify the following:
- Pressure, p.
- Volume ratio, J (current volume/original volume).
- For a viscoelastic material model, the values depend on the value of the *time* member of the [Viscoelastic](https://help.3ds.com/2022/english/DSSIMULIA_Established/SIMACAEKERRefMap/simaker-c-viscoelasticpyc.htm?ContextScope=all) object.
- If *time*=RELAXATION_TEST_DATA, the table data specify the following:
- Normalized volumetric (bulk) modulus kR(t),(0≤kR(t)≤1).
- Time t (t>0).
- If *time*=CREEP_TEST_DATA, the table data specify the following:
- Normalized volumetric (bulk) compliance jK(t),(jK(t)≥1).
- Time t (t>0).
The corresponding analysis keywords are:
- VOLUMETRIC TEST DATA

Parameters
----------
table
A sequence of sequences of Floats specifying the items described below.
volinf
None or a Float specifying a normalized volumetric value that depends on the value of
the *time* member of the Viscoelastic object. The default value is None.If
*time*=RELAXATION_TEST_DATA, *volinf* specifies the value of the long-term, normalized
volumetric modulus, kR(∞). If *time*=CREEP_TEST_DATA, *volinf* specifies the value of
the long-term, normalized volumetric compliance, K(∞).This argument is valid only for a
viscoelastic material model.
smoothing
None or an Int specifying the value for smoothing. If *smoothing*=None, no smoothing is
employed. The default value is None.
temperatureDependency
A Boolean specifying whether the data depend on temperature. The default value is OFF.
dependencies
An Int specifying the number of field variable dependencies. The default value is 0.
Returns
-------
A VolumetricTestData object.
