Using the crack‐growth model, the deviation of real fracture stress from the stressing level measured by stepwise incremental loading with three starting modes is calculated. For both static and dynamic fatigue, the relative error depends only on the relative increment size and the crack‐growth parameter, n. The usefulness of stepwise incremental loading for strength testing can be confirmed.
