Abstract

We propose an energy version of the theory of creep for initially isotropic materials containing parallel plane microcracks and deduce constitutive equations of creep and the kinetic equation of accumulation of damage. We consider basic experiments aimed at the determination of material constants according to the proposed theory. The theoretical results are compared with the experimental data obtained for a light alloy with different resistance to tension and compression.
