ceramicbearing: Rolling contact fatigue of ceramic ball bearings

In Auburngrads/SMRD: Statistical Methods For Reliability Data

Description

McCool gives the results of a rolling contact fatigue test of ceramic ball bearings. Ten specimens were tested across four levels of stress measured in kilo-Newtons (1 kN = 1000 N).

Format

A data.frame with 69 rows and 5 variables:

[, 1]	kilocycles	Accumulated cycles at event (in thousands)	Numeric
[, 2]	mode	Failure mode observed at kilocycles	Categoric
[, 3]	event	Event observed at kilocycles (failure/right-censored/left-censored/interval-censored)	Categoric
[, 4]	count	Number of events observed at kilocycles	Numeric
[, 5]	kilonewtons	Applied stress (in thousands)	Numeric
