Weibull Analysis of H-451 Nuclear-Grade Graphite

Abstract

This paper presents the estimation of Weibull parameters by Least Square Method and Maximum Likelihood Method. Experimental data of H-451 nuclear-grade graphite have been taken for evaluation. A computer program has been developed for the analysis of two parameter Weibull distribution. It is illustrated that maximum likelihood estimator gives more accurate values of Weibull model in comparison to least square estimation. Weibull parameters estimated from two methods are match well with the results given in referred paper. © 2016 The Authors.
