Can ANSYS Model creep behavior from Larson Miller Parameter data?

      The Larson-Miller Parameters are derived from a general expression of the Arrhenius Equation. We do not have a creep material model expressed directly in terms of the LMP data, but we do have three expressions for the Arrhenius equation. (TBOPT=2,6 or 13). One could conceivably back calculate the parameters for Arrhenius equation from available LMP data. See attached derivation.
