Investigation of Reliability of Strength Values Measured on CFRP (Carbon Fiber Reinforced Plastics) Test Bars by Statistical Methods. Part 1. Probability Distributions for Strength Analysis

摘要

Statistical distribution of order-value analysis, of the corresponding estimation functions for the plotted positions of the estimated value of the total frequency to be allocated to each observed value (fracture probability), of probability models particularly relevant to material testing, of graphic/numerical data analysis and the estimation of characteristic values, and the reliability of life predictions are reviewed. Computer and plotter programs make it possible to display Gaussian normal distribution, log normal distribution, and Weibull distribution together with their distribution laws, characteristic degrees of scatter, parameters of form, position and scale, and curve patterns for distribution density, distribution function, and failure rate, and the corresponding probability networks including measurement points, regression lines and reliability limits.
