Based on the consideration that the phenomena of fracture of rubber vulcanizates are extremal, the third asymptote of the smallest values has been applied to the distribution of tensile data of SBR vulcanizates. The influences of some factors such as rubber polymers, curing systems, fillers, and testing conditions on the distribution of tensile data have also been investigated. The assumed systematic behaviours of these factors can give the reasonable explanation for the application of this function to the distribution of observations.As a result of this series of papers, the conceptual distribution function is derived herein by using the largest flaw theory. The following are postulated through this study: The rubber vulcanizates fractures at the location of the largest flaw contained in the matrices and in a brittle behavior at a given strain rate under tension. Then, the physical implications on these parameters, including the size effects on the distribution of tensile data can be explicitly explained.
