AbstractThe result of a phenomenological study in the analysis of uniaxial and biaxial tensile behavior of a variety of filled systems is described. A correlation is given that appears to serve as a tensile failure criterion for most of the systems investigated. The storedenergy functionW, assumed to be equal to the area under the stress‐strain curve, has been found to obey the relationW=A(1 – exp {–B(Q– 3)}), whereAandBare constants andQis related to the first or second strain invariant. In general, the total stored energy up to break, divided byA, has a value between 0.7 and 0.8, which appears to be independent of strain rate and temperature. This constancy has also been verified by an independent set
