Monte Carlo simulation of Weibull distribution of ceramic strength values
Brittle engineering ceramics usually fail due to flaws that are distributed in the material. Their strength depends on the length of the major flaw, which may be different from specimen to specimen, being described by a probability function. If the material exibits a statistical distribution of independent flaws and the weak link hypothesis is fulfilled, i.e., the specimen fails if its weakest ...

متن کاملWeibull Rayleigh Distribution: Theory and Applications
For the first time, a three-parameter lifetime model, called the Weibull Rayleigh distribution, is defined and studied. We obtain some of its mathematical properties. Some structural properties of the new distribution are studied. The method of maximum likelihood and least squares methods is used for estimating the model parameters and the observed Fisher’s information matrix is derived. We ill...
متن کاملThe Weibull-power Function Distribution with Applications
Recently, several attempts have been made to define new models that extend well-known distributions and at the same time provide great flexibility in modelling real data. We propose a new four-parameter model named the Weibull-power function (WPF) distribution which exhibits bathtub-shaped hazard rate. Some of its statistical properties are obtained including ordinary and incomplete moments, qu...
متن کاملSome Statistical Inferences on the Parameters of Records Weibull Distribution Using Entropy
In this paper, we discuss different estimators of the records Weibull distribution parameters and also we apply the Kullback-Leibler divergence of survival function method to estimate record Weibull parameters. Finally, these estimators have been compared using Monte Carlo simulation and suggested good estimators.
