Question:
The limiting stress below which the material can be subjected to an infinite number of cycle without failure is called
The limiting stress below which the material can be subjected to an infinite number of cycle without failure is called
Show Hint
Endurance = Infinite life. It is the stress a material can "endure" forever.

- Maximum repeated stress
- Average stress
- True stress
- Endurance Limit
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept Fatigue is the failure of a material under fluctuating or cyclic loading at stress levels below the tensile strength.
Step 2: Meaning For many materials, especially steels, there is a specific stress level on an S-N curve where the curve becomes horizontal.
Step 3: Analysis Below this stress value, the material is theoretically capable of enduring an infinite number of load cycles without failing.
Step 4: Conclusion This critical stress value is technically known as the endurance limit or fatigue limit. Final Answer: (D)
