We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

      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.
