Abstract

The stress-strain relation for an aging material is obtained from an analysis of a four-element model of a viscoelastic body with variable coefficients. In this formulation the problem of calculating the rupture life is divided into four steps: a) solution of the boundary-value problem of the theory of elasticity of an incompressible material; b) calculation of the stationary thermal field; c) solution of the rheological equation at the danger point; d) solution of the criterial equation for the local fracture time. An example of the calculation of the high-temperature rupture life of a rubber cord under constant load is given. The agreement with experiment is satisfactory.
