While modern engineers use Finite Element Analysis (FEA) software to simulate stress on shafts, hand calculations are still required to validate the computer models. The analytical formulas found in ASME B106.1M serve as the baseline check. If an FEA result deviates significantly from the ASME calculation, it serves as a red flag that the model may be flawed.

One of the most significant contributions of the standard is its rigorous treatment of fatigue. A shaft rotating at 1,750 RPM undergoes over a million stress cycles in just 10 hours. A static calculation based on yield strength is insufficient for such dynamic loading.
