Cover cracking as a function of rebar corrosion: Part 2—Numerical model
Abstract A numerical model based on standard finite-element techniques is proposed for the simulation of cracking in concrete specimens when subjected to corrosion of their reinforcement. A smeared-crack approach is used to model the behaviour of the concrete finite elements, while the corrosion, which is understood as the applied load on the structure, is modelled by a combination of initial strains and change of elastic properties, which are respectively equivalent to the expansion and softening of the steel elements at the rebar surface when they rust. The model is applied to four examples, which were simultaneously tested experimentally and reported in Part 1 of this paper, and the influence of the main parameters of the model in the response is studied separately. In particular, the effect on the crack-width rate of the specific volume of the rust being formed is quantitatively assessed.
