The ductile material gives best result in the high strain amplitude or high cycle fatigue, while the strong material gives best result in high-stress low cycle fatigue.

The ductile material gives best result in the high strain amplitude or high cycle fatigue, while the strong material gives best result in high-stress low cycle fatigue. Correct Answer True

The ductile material can withstand high strain without failing, so it gives best performance in the high cycle fatigue. The strong material can resist the deformation without causing excessive deformation, so it performs well in high-stress low cycle fatigue.
