Tearing energies (T) have been evaluated for carbon-black-reinforced SBR tested in uniaxial tension. The influence of notch depth on T and fracture morphology have also been determined. The influence of notch depth on the stress-strain behavior and on the failure stress and failure strain is also illustrated. The ratio of recovered-to-input energy as a function of both stress and strain was determined for notched and notch-free samples.
