If the dynamic loads () remain below a material-specific threshold value (fatigue limit), the number of tolerable load cycles will be sufficient to attain the prescribed life span. Some materials, such as steels, can tolerate any number of load cycles below the fatigue limit (<a id="examples-for-thermomechanical-loads"></a><…
