..., so that mortality curves for groups of tests did not seem necessary. The difference between sleeve bearings and rolling bearings was thought to be primarily due to the ability of sleeve bearing flow under high local stress, thus providing some stress equalization for sleeve bearings ( Ref 27...

.... This decreases rapidly as shown in Fig. 6 . This period of decreasing failure rate is called various names, such as early life period, infant mortality period, and shakedown period. Failure occurs due to design or manufacturing weaknesses, that is, weak or substandard components. Fig. 6 Mortality curve...

.... The regression estimates cannot be expected to be precise because the estimation of the cooling time represents the minimum time for cooling and does not take into account the information of hot melt during packing or any curved (not slab like) sections in the part. Moreover, each plant is usually operated...
