N2 - We examine the crack paths in concrete due to reinforcement corrosion and investigate their influencing factors by performing numerical simulations of propagating cracks. In order to accurately simulate the initiation and propagation of cracks, we enhance the finite cover method (FCM) so as to work with regularly structured mesh without remeshing and characterize nonlinear behavior of process zone fracture by means of the cohesive crack model. The method enables us to not only reproduce the modes of crack paths reported in experimental studies by combining the mechanically correct model of reinforcement corrosion, but also evaluate the effect of initial condition and use environment of global structure for propagating cracks in local structures.
