A computer simulation for estimating lower bound fracture strength of composites using Weibull distribution
(Elsevier Sci Ltd, 2004) Birgoren, B; Dirikolu, MH
Estimating confidence lower bound for fracture strength of composites is a key concern in design and manufacture, and the Weibull distribution has been widely used for this purpose. Previous simulation-based studies presented computational tools for these bounds involving tables or parametric equations, which lack generality and may contain simulation and curve-fitting errors. An alternative approach is to present a fast and effective simulation tool that can be directly used by the end-user. Such a tool is developed in this study for estimating the bounds using the Weibull distribution based on maximum likelihood estimation. This is a more versatile approach in that it allows the user to input any desired confidence level, failure probability, and simulation-run number. The tool is demonstrated by using fracture strength data obtained from ASTM D3039 tension tests of 19 identical carbon-epoxy composite specimens. The results are compared with those obtained from previously developed approaches. (C) 2004 Elsevier Ltd. All rights reserved.
