BIAXIAL AND UNIAXIAL TENSILE PROPERTIES OF ELASTOMERS.

Abstract

Rupture of a styrene-butadiene vulcanizate in both biaxial and uniaxial tension at temperatures between 25 and 90 C is discussed. Biaxial data were obtained by stretching a thin-wall cylindrical specimen at different extension rates while the pressure inside the specimen was adjusted continuously to maintain a constant outside diameter. From the biaxial data the uniaxial tensile failure envelope was computed and was found to agree closely with the envelope given by experimental data. Uniaxial stress-strain and rupture data for a variety of unfilled vulcanizates are also discussed.
