    The table data for this object are:

    - If *hardening*=VOLUMETRIC, the table data specify the following:
        - Ratio, k, of initial yield stress in uniaxial compression, σc0, to initial yield stress in hydrostatic compression, p0cpc0; 0.0 <k< 3.0.
        - Ratio, kt, of yield stress in hydrostatic tension, pt, to initial yield stress in hydrostatic compression, pc0. The default value is 1.0.
        - 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 *hardening*=ISOTROPIC, the table data specify the following:
        - Ratio, k, of initial yield stress in uniaxial compression, σ0cσc0, to initial yield stress in hydrostatic compression, p00; 0.0 ≤k≤ 3.0.
        - Plastic Poisson's ratio.νpνp; -1≤νp≤0.5.
        - 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.
