This article discusses modeling of polymer corrosion in aggressive environments based on percolation theory. Within the framework of the work, an algorithm for modeling polymer corrosion was developed, and a program that implements this algorithm in C ++. Paper describes the corrosion modeling algorithm, the structure of the implemented program, and the simulation results for various parameters. The result of this work is an algorithm modeling and an application that performs modeling of the polymer corrosion process in aggressive environments based on the percolation theory according to the developed algorithm, as well as building an image of the damaged material, graphs of the dependence of the length of the boundary of the corrosion region and the area of the remaining material on the modeling step. Algorithm uses Monte-Carlo method for determing area of corrosing region and is suitable for parallel implementation.

Keywords: percolation theory, corrosion modeling, simulation of physical processes, Monte Carlo method, visualization of simulation results
