Card 6 / 36: How does creep differ from fatigue?
A)
Creep refers to slow deformation resulting in change in macroscopic shape; fatigue refers to the weakening of material over time caused by repeated use or loading.
B)
They do not differ.
C)
Creep refers to the overall weakening of a material through pressure; fatigue refers to the weakening that occurs at susceptible stress points.
D)
Creep is temperature dependent; fatigue is not.
E)
Creep is more significant for very large pieces than fatigue; fatigue is more important for small pieces that fail as a result of small-crack propagation.
Answer:
A) Creep refers to slow deformation resulting in change in macroscopic shape; fatigue refers to the weakening of material over time caused by repeated use or loading.
