The fatigue endurance limit of a material is defined as:
(A) The stress amplitude below which the material can endure an infinite number of cycles without failure
(B) The static ultimate tensile strength
(C) The stress at which necking begins
(D) The yield point at 0.2% offset strain
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Endurance limit (or fatigue limit) is the cyclic stress amplitude below which fatigue failure does not occur even after very large (>10^7) numbers of cycles. Correct: A.
