摘要：
Thin specimens of a black-filled, natural rubber vulcanizate have been held in uniaxial tension at 72 °C and 200% elongation in a forced air oven. After substantial oxidative attack (inferred from stress relaxation), small edge cracks formed. Initially, these cracks grew perpendicular to the loading direction, but, upon reaching about 0.1 mm in depth, longitudinal crack growth commenced and fracture progressed by a kind of 0°-peel process with `splitting-off' of successive strands of rubber. This phenomenon is attributed to anisotropy in strength caused both by straining and by oxidative attack.
