FIGURE 4.5
The relation between relative fraction of loosely packed matrix j
l.m.
and
probability of elastic state realization c for PC (1) and PAr (2) [23].
In Fig. 4.5, the comparison of values c and j
l.m.
for PC and PAr is ad-
duced, which has shown their good correspondence. The data of this figure
assume that the loosely packed matrix can be identified as the elastic defor-
mation region and clusters are identified as the region of inelastic (plastic)
deformation [23]. These results prove the conclusion made in the Ref. [22]
about proceeding of inelastic deformation processes in dense packing re-
gions of amorphous glassy polymers and indicate correctness of the plastic-
ity fractal theory at their description.
