VolumetricTestData(...)

This method creates a VolumetricTestData object.

Path

mdb.models[name].materials[name].viscoelastic.VolumetricTestData

Required arguments

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

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, jK⁢(∞).

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.

Table data

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 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).

Return value

A VolumetricTestData object.

Exceptions

None.

setValues(...)

This method modifies the VolumetricTestData object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the VolumetricTestData method.

Return value

None.

Exceptions

None.

Members

The VolumetricTestData object has members with the same names and descriptions as the arguments to the VolumetricTestData method.
