av M FRÖLING · Citerat av 8 — MPa, ν = 0.43 (PVB) are used, where E denotes modulus of elasticity and ν is combined with a Weibull-description of glass strength in order to provide a

Therefore, the best rate of rising voltage in the electric breakdown test is 2 kV/s which gives the same results as the mechanical tests. Accuracy of the LS methods for Weibull modulus and characteristic strength essentially depend on plotting position and sample size. Large sample sizes (n≥30) support a credible Weibull parameters estimation. An important complement of the point estimates of Weibull parameters is provided by the Menon 95%CI. Using Weibull analysis to do probabilistic failure design. Determining what stress will yield an arbitrarily defined survival or failure rate. Effective area Weibull-Modul.

El módulo de Weibull es un parámetro adimensional de la distribución de Weibull que se utiliza para describir la variabilidad en la resistencia medida de los materiales quebradizos. Para cerámicas y otros materiales quebradizos, la tensión máxima que puede resistir una muestra antes de fallar puede variar de una muestra a otra, incluso en condiciones de prueba idénticas.

between Weibull Modulus estimates based on strength distribution and those based on size. The sketch below shows a typical stress distribution when some

The Weibull modulus has been considered as a material parameter with its constant value describing the degree of size effect. The main tendency of size effect in brittle materials is that a more brittle material commonly produces a lower value of m. Accuracy of the LS methods for Weibull modulus and characteristic strength essentially depend on plotting position and sample size. Large sample sizes (n≥30) support a credible Weibull parameters estimation.
