Required arguments

table

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

Optional arguments

smoothing

None or an Int specifying the value for smoothing. If smoothing=None, no smoothing is employed. The default value is None.

lateralNominalStrain

A Boolean specifying whether to include lateral nominal strain. The default value is OFF.

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 material model, the table data specify the following:

  • Nominal stress, TU.

  • Nominal strain, ϵU.

For a hyperfoam material model, the table data specify the following:

  • Nominal stress, TL.

  • Nominal strain, ϵU.

  • Nominal lateral strain, ϵ2=ϵ3. The default value is 0.

For a low-density foam material model, the table data specify the following:

  • Nominal stress, TU.

  • Nominal strain, ϵU.

  • Nominal strain rate, ϵU˙.

Return value

A UniaxialTestData object.

Exceptions

None.

setValues(...)

This method modifies the UniaxialTestData object.

Required arguments

None.

Optional arguments

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

Return value

None.

Exceptions

None.

Members

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