Conclusions

  1. 1.

    Using as an example partially crystallized high-density polyethylene polymer, the existence of an incubation period preceding the start of failures on a molecular level was observed.

     
  2. 2.

    The use of a model of failure taking into consideration the statistical distribution of overstresses in the bonds provides qualitatively good agreement of calculation and experimental results in the area of steady and spontaneously accelerated accumulation of damages.
