홈 벽 항복(Groove Wall Yielding)'이란 무엇이며 이것이 치명적인 조립 실패로 이어지는 이유는 무엇입니까?

Groove wall yielding occurs when the axial stress $σ_a$ applied by the retaining ring exceeds the yield strength $σ_y$ of the housing or shaft material. This stress is $σ_a = \frac{P}{\pi \cdot D \cdot d}$. As the wall yields, it creates a 'ramp' effect. Under cyclic loading, the ring 'walks' up this ramp until it clears the groove. This is 'catastrophic'...
