چکیده انگلیسی
The current study aims to associate the Weibull probability equations to the ones commonly used when modeling the S-N curves of composite materials, which are the exponential equation and the power law and its generalizations. The association among them will be called as the “Probabilistic S-N Curves”. In order to evaluate and compare the results of such associations, a database containing three composite materials was used. Such materials are known as the following abbreviations: DD16, IM7/977 and T800/5245. The results obtained from the probabilistic S-N curves were compared to the probabilistic outcomes of each stress level that had been analyzed. The results indicate that the probabilistic S-N curves based on the generalized power law reproduce the physical phenomenon in a better way.
