metadata.value: During the prolonged action of mechanical stresses and moderate temperatures the interrelated processes
  of deformation and damage in polymer materials are occured. These processes lead to destructive effects
  and are accompanied by chemical reactions, which increase the structure changes and properties of the
  considered materials. Accordingly, it is possible to distinguish two types of fracture of polymeric materials
  during long-term mechanical and thermal effects. The first type (mechanical) is implemented in the
  condition of active loading, and in experiments on creep at moderate temperatures. The second type of
  fracture (chemical) is associated with the accumulation of structural damage in the long process of aging in
  the absence of external stress (static fatigue). The modified version of Maxwell’s equation and the equation
  for the damage parameter are formulated. The analytical solutions for the creep and stress relaxation are
  derived. Unlike Maxwell formula, the stress relaxation ratio has not zero asymptote. To describe the creep
  deformation and fracture of a compressible elastic-viscous medium the Boltzmann Volterra equation is
  used. An analytical solution for the continuity parameter and the long-term strength criterion is received.
  The theoretical curves for the continuity parameter and the long-term strength criterion are plotted.
  Quantitative and for creep curves qualitative agreement with the corresponding experimental curves are
  observed. Refs 12. Figs 6.
