  • Analysis of crack-paths in concrete due to reinforcement corrosion and their underlying mechanism

抄録

By performing numerical simulations of propagating cracks in concrete due to reinforcement corrosion, we illustrate various modes of crack paths according to the thickness of overburden for reinforcing steel, and investigate their underlying mechanisms. In order to accurately simulate the initiation and propagation of cracks, we enhance the finite cover method (FCM) so as to working 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, but also predict the deterioration of concrete.
