The article describes the mechanism of the elastic interaction between local micro-
defects, called holes, which are formed and accumulated in the area of forced elasticity
in front of the crack fracture in polymers. We calculated the elastic fields of holes, their
own elastic energy, interaction energy of holes and the strength of their pair interaction.
It is shown that the interaction between the holes leads to the fact that each hole is sur-
rounded by a cluster of smaller holes
.
Keywords:
elastic fields, local microcracks
,
strained polymers and composites.
