    This object can be accessed by:

    .. code-block:: python

        import material

    The table data for this object are:

    - If **type** = ISOTROPIC, the table data specify the following:
    
        - :math:`\alpha` in Abaqus/Standard or Abaqus/Explicit analysis.
        - Temperature, if the data depend on temperature.
        - Value of the first field variable, if the data depend on field variables.
        - Value of the second field variable.
        - Etc.
    - If **type** = ORTHOTROPIC, the table data specify the following:
    
        - :math:`\alpha_{11}`.
        - :math:`\alpha_{22}`.
        - :math:`\alpha_{33}`.
        - Temperature, if the data depend on temperature.
        - Value of the first field variable, if the data depend on field variables.
        - Value of the second field variable.
        - Etc.
    - If **type** = ANISOTROPIC, the table data specify the following:
    
        - :math:`\alpha_{11}`.
        - :math:`\alpha_{22}`.
        - :math:`\alpha_{33}`. (Not used for plane stress case.)
        - :math:`\alpha_{12}`.
        - :math:`\alpha_{13}`.
        - :math:`\alpha_{23}`.
        - Temperature, if the data depend on temperature.
        - Value of the first field variable, if the data depend on field variables.
        - Value of the second field variable.
        - Etc.
    - If **type** = SHORT_FIBER, there is no table data.

        Parameters
        ----------
        type
            A SymbolicConstant specifying the type of expansion. Possible values are ISOTROPIC,
            ORTHOTROPIC, ANISOTROPIC, and SHORT_FIBER. The default value is ISOTROPIC.
        userSubroutine
            A Boolean specifying whether a user subroutine is used to define the increments of
            thermal strain. The default value is OFF.
        zero
            A Float specifying the value of :math:`\theta_0` if the thermal expansion is temperature-dependent or
            field-variable-dependent. The default value is 0.0.
        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
            A sequence of sequences of Floats specifying the items described below. The default
            value is an empty sequence.This argument is required only if **type** is not USER.

        Returns
        -------
        Expansion
