Use of Weibull Statistics to Correlate MOR, Ball‐on‐Ring, and Rotational Fast Fracture Tests

Fast fracture strength data on slip-cast reaction-bonded Si3N4 determined by uniaxial MOR, biaxial ball-on-ring tests, and speed of rotational failure measurements were correlated using Weibull statistics and finite-element techniques. The agreement between predicted and observed values demonstrated the applicability of the Weibull equation.
