Some factors affecting the flex life of polybutadiene rubber vulcanisate by Muhammad Farooq, Ali Ansarifar

“…The mechanical properties of the rubber vulcanisates such as tensile strength, Young’s modulus, elongation at break, stored energy density at break and tear energy were subsequently determined. The flex life of the rubber vulcanisates was also measured at a constant maximum strain amplitude and a test frequency of 3.17 Hz at ambient temperature. …”
