Match the stages of fatigue failure.
Group of answer choices
Stage I
[ Choose ] Micro-crack initiation caused by cyclic plastic deformation. N/A Progresses to a macro-crack that repeatedly opens and closes, forming bands known as beach marks. The crack has propagated to the point where the remaining material can't support the load and fails by simple ultimate failure.
Stage II
[ Choose ] Micro-crack initiation caused by cyclic plastic deformation. N/A Progresses to a macro-crack that repeatedly opens and closes, forming bands known as beach marks. The crack has propagated to the point where the remaining material can't support the load and fails by simple ultimate failure.
Stage III
[ Choose ] Micro-crack initiation caused by cyclic plastic deformation. N/A Progresses to a macro-crack that repeatedly opens and closes, forming bands known as beach marks. The crack has propagated to the point where the remaining material can't support the load and fails by simple ultimate failure.
