For ceramics and other brittle materials, the maximum stress that a sample can be measured to withstand before failure may vary from specimen to specimen, even under identical testing The Weibull modulus is 20.3, although again there is a trend for a greater size effect for the larger two sets of specimens than for the smaller two sets. The shear strength of the 8 mm specimens is similar to the value for the 6.4 mm specimens from the previous results for specimens cut from the thick plate, but the strengths of the 2 and 4 mm specimens made from thinner plates are higher than the previous ones.

av D Jehpsson — design and the elastic modulus of the cement.

The spread of strengths is related to the Weibull modulus, m, which is typically in the range 3 to 15 for polished optical ceramics. The larger the value of m, the narrower is the distribution of strength.

The Weibull modulus is a dimensionless parameter of the Weibull distribution which is used to describe variability in measured material strength of brittle materials.. For ceramics and other brittle materials, the maximum stress that a sample can be measured to withstand before failure may vary from specimen to specimen, even under identical testing conditions. Weibull modulus. The Weibull modulus or Weibull distribution describes the lifetime and frequency of failure of brittle materials. The theory is based on the concept of the weakest link.

Weibull modulus Strength scaling Maximum likelihood Linear regression abstract Objectives. To review the history, theory and current applications of Weibull analyses sufﬁ-cient to make informed decisions regarding practical use of the analysis in dental material strength testing. Weibull probability plot: We generated 100 Weibull random variables using $$T$$ = 1000, $$\gamma$$ = 1.5 and $$\alpha$$ = 5000.
