Query: Modeling Acoustic Emission in Microfracturing Phenomena   It has been recently observed that synthetic materials subjected to an
external elastic stress give rise to scaling phenomena in the acoustic emission
signal. Motivated by this experimental finding we develop a mesoscopic model in
order to clarify the nature of this phenomenon. We model the synthetic material
by an array of resistors with random failure thresholds. The failure of a
resistor produces an decrease in the conductivity and a redistribution of the
disorder. By increasing the applied voltage the system organizes itself in a
stationary state. The acoustic emission signal is associated with the failure
events. We find scaling behavior in the amplitude of these events and in the
times between different events. The model allows us to study the geometrical
and topological properties of the micro-fracturing process that drives the
system to the self-organized stationary state.
