The Effect of Stress Relaxation on the Tearing of Vulcanized Rubber
A two-network model for an elastomer in which stress relaxation has taken place, similar to that proposed by Green and Tobolsky, is used to calculate the incipient characteristic energy for tearing and to study its dependence on the number of chain segements in each of the two networks, the number of links in these chain segments, the extension at which the stress relaxation took place and the orientation of the tear.
