    This object can be accessed by:

        import odbMaterial
        session.odbs[name].materials[name].concrete.tensionStiffening

    The table data for this object are:

    - If **type** = STRAIN, the table data specify the following:
    
        - Fraction of remaining stress to stress at cracking.
        - Absolute value of the direct strain minus the direct strain at cracking.
        - 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** = DISPLACEMENT, the table data specify the following:
    
        - Displacement, u0u0, at which a linear loss of strength after cracking gives zero stress.
        - 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.

        Parameters
        ----------
        table
            A sequence of sequences of Floats specifying the items described below.
        type
            A SymbolicConstant specifying how the postcracking behavior is defined. Possible values
            are DISPLACEMENT and STRAIN. The default value is STRAIN.
        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.
