Required arguments
Optional arguments
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.
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.
A Boolean specifying whether to invoke the optional
reset procedure described in Section 4.3.5 of the Nuclear Standard. The default value is OFF.
Return value
An Ornl object.
Exceptions
RangeError.
This method modifies the Ornl object.
Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the Ornl method.
Return value
Exceptions
RangeError.
The Ornl object has members with the same names and descriptions as the arguments to the Ornl method.
