Abstract
We consider a network, bonds of which are being sequentially
removed; that is done at random, but conditioned on the system
remaining connected (Self-Repairing Bond Percolation SRBP). This
model is the simplest representative of a class of random systems
for which forming of isolated clusters is forbidden. It
qualitatively describes the process of fabrication of artificial
porous materials and degradation of strained polymers. We find a
phase transition at a finite concentration of bonds p=pc, at
which the backbone of the system vanishes; for all p<pc the
network is a dense fractal.
