Abstract
The possibility of using advances in the kinetic theory of strength for predicting the performance of polymers is analyzed. It is shown that the theory provides a scientific basis for predicting the life of polymers under load not only in uniaxial tension at constant stress, when the basic lifetime equation with constant coefficients τ0, U0, and γ holds, but also in the presence of various complications — in the region of small stresses and high temperatures, in the presence of structural changes during service, in complex loading regimes (including cyclic loading) and complex states of stress, and, moreover, when the stressed polymer is exposed to radiations or aggressive media.
