Abstract
Section titled āAbstractāAbstract : This report provides a tutorial on the Weibull distribution of strength of ceramic materials and the use of the maximum likelihood method of American Society for Testing and Materials (ASTM) C1239 to obtain Weibull parameters from a set of test coupons. Parameters compiled from test data of infrared window materials are used to predict the static probability of failure of an optical window in the absence of slow crack growth. This report emphasizes how the strength of a window scales inversely with the size of the window. Test data are given for aluminum oxynitride (ALON), calcium fluoride, chemical vapor deposited (CVD) diamond, fused quartz, germanium, magnesium fluoride, yttria-magnesia nanocomposite optical ceramic (NCOC), polycrystalline alumina, sapphire (a-plane, c-plane, and r-plane), magnesium aluminum spinel, yttria, zinc selenide, and zinc sulfide (standard and multispectral grades).
