stress66: Breaking Stress of 66 Carbon Fibers of Length 50 mm

Description

This dataset contains the breaking stress (in GPa) of 66 carbon fibers of length 50 mm. The data were originally used by Nichols and Padgett (2006) in their study on bootstrap control charts for Weibull percentiles.

Usage

stress66

Value

An object of class "numeric".

The vector consists of 66 observed breaking stress measurements (in gigapascals) for individual carbon fiber specimens of length 50 mm. Each value represents the stress level at which a single fiber failed. The dataset is commonly used in reliability analysis, survival modeling, and goodness-of-fit studies involving strength and lifetime distributions, particularly Weibull models and bootstrap-based control charts.

Format

A numeric vector of length 66 containing breaking stress values measured in gigapascals (GPa).

Details

The carbon fiber breaking stress dataset is commonly used in reliability analysis, survival models, and goodness-of-fit studies involving lifetime and strength distributions. Nichols and Padgett (2006) applied these data in developing bootstrap control charts based on Weibull percentiles.
