Paper Title:
Effects of Notch Size on Strength Distribution of Ceramic Components
  Abstract

The dependence of strength on notch radii of ceramic components is presented. The strength is exponential decay as the notch radius decrease, the smooth specimen that corresponds to the infinity notch radius topped the fracture strength, but the lowest value relys on the micro feature of the materials. Plotted the strengths on Weibull and Normal probability paper, the fitness coefficients reveal that the strength of smooth specimen, as the past literatures indicated, follows Weibull distribution, but the strength of notched specimen follows Normal distribution better. Such result is due to the fact that the decreasing notch radius reduces and limits the effective original fracture volume, when the notch becomes a slim crack, the weakest link place becomes deterministic.
