Answer
In a Shear Failure, the ring itself is cut into two pieces along its circumference. Sifas echèk la ap parèt tankou yon zòn ki klere, ki te bruni ki te swiv pa yon ka zo kase ki graj, ki endike ke estrès taye $\tau = P / (\pi D t)$ depase fòs taye materyèl la ($~0.6 \time UTS$). Groove Yielding, sepandan, karakterize pa miray la Groove yo te pouse tounen oswa 'woule' sou. Bag la ka rete entak men yo pral 'plate' oswa defòme. Dyagnostik se senp: si Groove a toujou byen file ak nan tolerans men bag la taye lenn, materyèl bag la pa t ase. If the groove is deformed and the ring 'popped out', the housing material was too soft or the groove was too shallow for the applied load.
