Utarmning: Uppstår särskilt have been discussed as volume effects within the concept of Weibull statistics Weibull modulus was not obtained from the limited number of fatigue tests. In comparison with other dental materials, the highest value of the Weibull modulus could be achieved.

Glass Failure and Weibull Statistics m o f − = σ σ σ (σ) µ • Glass failure does not follow normal statistics • Weibull generated a new approach for brittle materials. • σµ= threshold failure stress • σo = characteristic stress • m = Weibull modulus ariability in datastandard deviationsthe weibull equationworked example for strength at specific failure rate scaling from test bars to components using effe 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 Analysis is an effective method of determining reliability characteristics and trends of a population using a relatively small sample size of field or laboratory test data. The toughness data of five different nuclear reactor and containment vessel steels are analyzed. The estimations obtained the Weibull modulus (m) in the range of 1.83 to 2.55 and strong temperature dependence of the threshold cleavage fracture toughness Kmin, as opposed to the constant values of mK = 4 and Kmin = 20 MPam1/2 given in ASTM E1921-19. The Weibull statistical distributions of the tensile strength were also characterized.

The Maximum Likelihood method and the Linear Least Squares (LLS) method have been widely used to estimate Weibull parameters for reliability of brittle and metal materials. In the last 30 years, many researchers focused on the bias of Weibull modulus estimation, and some improvements have been achieved, especially in the case of the LLS method. However, there is a shortcoming in these methods
