Card 8 / 36: Which of the following best describes the process of fatigue for engineering materials?
A)
Fatigue is material corrosion that prevents further use.
B)
Fatigue is the failure or weakening of material caused by repeated or continued stress or loading
C)
Fatigue is the natural aging of material that leads to failure.
D)
Fatigue is the weakening of engineering materials caused by thermal cycling and the resulting molecular rearrangements that occur.
E)
Fatigue is the temporary weakening of materials resulting from continued use; materials may recover strength if random molecular rearrangements are allowed to occur during a period of disuse.
Answer:
B) Fatigue is the failure or weakening of material caused by repeated or continued stress or loading
