Monte Carlo Simulation Method for Pit Erosion Process of Cable Wire Based on Bi-plane Cellular Automata

Abstract

This paper proposed a new probabilistic Bi-plane cellular automaton (CA) model to simulate the localized pitting corrosion of stayed cables. The CA model introduced chloride ions and their evolution rules to take into account the local acidification catalysis is in microscopic scale. Besides, a Monte Carlo approach is adopted to analyze the statistical properties of corrosion pit size and their variation with respect to time. The proposed CA model is confirmed by several published experiments on pitting corrosion. It is capable to reproduce the experimental observations and enlarge the sample space for subsequent mechanical analysis.
