CombinedTestData(...)

This method creates a CombinedTestData object.

Path

mdb.models[name].materials[name].viscoelastic.CombinedTestData
session.odbs[name].materials[name].viscoelastic.CombinedTestData

Required arguments

table

A sequence of sequences of Floats specifying the items described below. The values of the table data depend on the value of the time member of the Viscoelastic object.

Optional arguments

volinf

None or a Float specifying a normalized volume. The value of volinf 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(∞).

shrinf

None or a Float specifying a normalized shear. The value of shrinf depends on the value of the time member of the Viscoelastic object. The default value is None.

If time=RELAXATION_TEST_DATA, shrinf specifies the value of the long-term normalized shear modulus, gR(∞).

If time=CREEP_TEST_DATA, shrinf specifies the value of the long-term normalized shear compliance, jS(∞).

Table data

If time=RELAXATION_TEST_DATA, the table data specify the following:

  • Normalized shear modulus, gR(t) (0≤gR(t)≤1).

  • 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 shear compliance, jS(t) (jS(t)≥1).

  • Normalized volumetric (bulk) compliance, jK(t) (jK(t)≥1).

  • Time t (t>0).

Return value

A CombinedTestData object.

Exceptions

None.

setValues(...)

This method modifies the CombinedTestData object.

Required arguments

None.

Optional arguments

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

Return value

None.

Exceptions

None.

Members

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