Time to Failure {DataSetsUni}

Time to failure of kevlar 49/epoxy strands tested at various stress levels

Description

The function allows to provide the stress-rupture life of kevlar 49/epoxy strands that are subjected to constant sustained pressure at the 90 percent stress level until all have failed, so that the complete data set with the exact times of failure is recorded.

Usage

data_Kevlar

Arguments

data_Kevlar

A vector of (non-negative integer) values.

Details

The data refer to in the 101 data points represent the stress-rupture life of kevlar 49/epoxy strands that are subjected to constant sustained pressure at the 90 percent stress level until all have failed, so that the complete data set with the exact times of failure is recorded. Recently, it is used by Oluyede et al. (2018) and fitted a new Burr XII-Weibull-logarithmic distribution.

Value

data_Kevlar gives the stress-rupture life of kevlar 49/epoxy.
