Numerical Simulation of Steel Corrosion Expansion Based on Finite Element Method

Steel corrosion is a major reason for the durability of reinforced concrete structures. The simulation of steel corrosion is the key to predict the life of concrete. This paper summarized the simulation methods of steel corrosion and had an equivalent simulation to steel corrosion based on the principle of thermal expansion and contraction. Finally, according to this method the destructive process of reinforced concrete beams was successfully simulated.
