        Parameters
        ----------
        a
            A Float specifying the saturation rates for kinematic shift caused by creep strain, as 
            defined by Equation (15) of Section 4.3.3–3 of the Nuclear Standard. The default value 
            corresponds to that section of the Standard. Set *a*=0.0 to use the 1986 revision of the 
            Standard. The default value is 0.3. 
        h
            None or a Float specifying the rate of kinematic shift with respect to creep strain 
            [Equation (7) of Section 4.3.2–1 of the Nuclear Standard]. If *h*=None, the value of *h* 
            is determined according to Section 4.3.3–3 of the 1981 revision of the Standard. Set 
            *h*=0.0 to use the 1986 revision of the Standard. The default value is None. 
        reset
            A Boolean specifying whether to invoke the optional αα reset procedure described in 
            Section 4.3.5 of the Nuclear Standard. The default value is OFF.
