An integrated finite element based modelling approach is presented, which allows forfully coupled simulation of reinforcement corrosion and corrosion-induced concretedamage. While a finite element method (FEM) based corrosion model was used todescribe electrochemical processes at the reinforcement surface, a FEM based mechanicalmodel was used to simulate corrosion-induced concrete damage. Both FEMmodels were fully coupled, i.e. information, such as corrosion current density, damagestate of concrete cover, etc., were constantly exchanged between the models.To demonstrate the potential use of the modelling approach, a numerical example ispresented which illustrates full coupling of formation of corrosion cells, propagation ofcorrosion, and subsequent development of corrosion-induced concrete damage.
