- Аннотация: Presently there are two basic approaches to the problem of fracture in solids: mechanical and kinetic. The first approach uses as a fracture criterion the limiting state concept upon the attainment of which fracture occurs. The limiting state is in the general case a functional of the stress tensor, the strain, the strain rate, as well as the time and other factors affecting the fracture process. The second approach (kinetic) developed by S. N. Zhurkov and other investigators [1-3] studies fracture as an accumulation of microcracks under the effect of an external stress and local energy flucruations. In the present work the kinetics of crack growth are considered in quasibrittle amorphous polymers using a combination of both approaches. The stress fields and the strains close to the tip of the growing crack are computed from equations in mechanics and the crack growth rate is determined by the thermally fluctuatiing criterion of bond brealing.
