Abstract


The present work intends to analyze and numerically model the corrosion process, estimating the service life of concrete structures. The modelling process was divided in two stages, initiation and propagation. The modeling of the initiation phase was carried out by Artificial Neural Networks (ANN), and the modeling of the propagation phase was done by means of Finite Element Method (FEM). The results show the efficiency of the model generated by the coupling of ANN to the FEM to analyze and study the durability of reinforced concrete structures under uniform corrosion, and the numerical model applicability to estimate the service life of reinforced concrete structures.
