        Parameters
        ----------
        elementRemoval
            A Boolean specifying whether elements are removed if exceeding maximum principal tensile 
            stress. This argument is valid only when *maxAllowablePrincipalStress* is defined. The 
            default value is OFF. 
        maxAllowablePrincipalStress
            None or a Float specifying the maximum allowable principal tensile stress. The default 
            value is None. 
        extrapolateStressStrainCurve
            A Boolean specifying whether the stress-strain curve is extrapolated if exceeding 
            maximum strain rate. The default value is OFF. 
        strainRateType
            A SymbolicConstant specifying strain rate measure used for constitutive calculations. 
            Possible values are PRINCIPAL and VOLUMETRIC. The default value is VOLUMETRIC. 
        mu0
            A Float specifying the relaxation coefficient μ0. The default value is 10–4. 
        mu1
            A Float specifying the relaxation coefficient μ1. The default value is 0.5×10–2. 
        alpha
            A Float specifying the relaxation coefficient α. The default value is 2.0.
