摘要
The modulus of rupture or flexural strength of dental composites aged in distilled water and saline solution or cyclic-fatigued to fracture in distilled water was analyzed by use of Weibull statistics. Two- and three-parameter Weibull models were applied to the data. For the case of the dental composites aged for five distinct time periods, the most appropriate model was a two-parameter Weibull model for each separate aging time. For the cyclic-fatigue data, a three-parameter accelerated failure time model with a Weibull baseline distribution and scale parameter, depending on the variable cycle, was appropriate.
