at7987: Fatigue life test (alloy T7987)

In Auburngrads/SMRD: Statistical Methods For Reliability Data

Description

A test was conducted to assess the fatigue life of an alloy, designated as T-7987. In this test, 72 specimens were subjected to an unreported load spectrum. The number of cycles at which a specimen failed was recorded (rounded to the nearest thousand cycles). Of the 72 units tested, 67 units failures were observed and 5 units were right censored at 300 kilocycles.

Format

A data.frame with 68 rows and 3 variables:

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