titanium2: Titanium Alloy Fatigue Crack Growth

In Auburngrads/SMRD.data: Statistical Methods For Reliability Data - Datasets

Description

A sample of 100 specimens of a titanium alloy were subjected to a fatigue test to determine time to crack initiation. The test was run up to a limit of 100,000 cycles. The observed number of cycles to crack initiation (in units of 1,000 of cycles) were: 18, 32, 39, 53, 59, 68, 77, 78, 93. No crack had initiated in any of the other 91 other specimens prior to reaching 100,000 cycles.

Format

A data.frame with 10 rows and 3 variables:

[, 1]	kilocycles	Accumulated cycles at event	Numeric
[, 2]	event	Event observed at cycles (failure/right-censored)	Categoric
[, 3]	count	Number of events observed at cycles	Numeric
