Failure of a material is termed as fatigue failure, if it fails below the yield point. The resistance to fatigue failure of a material is measured by the__________________?
Correct answer: B. Endurance limit
- A. Ultimate tensile strength (U.T.S.)
- B. Endurance limit
- C. Elastic limit
- D. None of these
Explanation
The endurance limit is the maximum repeated or alternating stress a material can withstand without fatigue failure, usually below its yield stress. Ultimate tensile strength measures failure under a single tensile load, not cyclic loading.
