Simulation of a scalar fracture model based on Freitas (2007)

Simulates a fracture system using an electrical circuit, modeling forces as electrical currents over fuses and the breakages as fuses blowing. This allow for a similar study but in a much simpler computational setting, as electrical currents and potential difference are scalar values as opposed to forces and Hooke's law, which deal with vectors.

The simulation is based on the principle that our circuit is divided in sectors, and a current comes from an source point and moves through the circuit sector by sector, in which we check its transmition from the input wires on a contact to its output wires, where the proportion of the output current on each wire is inverse to its resistance. After distributing the current the wire is checked to see if the current is over its maximum value, and if it is the wire is removed from circuit. This process goes until there is no path connecting the source point to the destination point, i.e. there's no current flowing in the circuit anymore.
