THE TRIAXIAL TENSION FAILURE OF VISCOELASTIC MATERIALS

Abstract

After reviewing present work in failure criteria for various stress states, this report presents both an analytical and theoretical study of triaxial failure of polymeric materials. The configuration chosen for the investigation is a thin, circular, disk-like specimen that is bonded between rigid, cylindrical bars and pulled parallel to its longitudinal axis. Using the minimumtial energy principle, a stability criterion for catastrophic fracture for spherical voids is made, including details of local stresses and strains at the point of fracture, for finite as well as infinitesimal strains. Preliminary correlations of these results with more general failure theories including strain rate and temperature effects for uniaxial and biaxial stress states are indicated.
