This paper attempts the applications of an analytical and numerical approaches to simulation of concrete cracking due to corrosion of reinforcement, At first, a combination and detailed analysis of two analytical models proposed by Liu and Weyers (1998) and Li et al. (2006) is presented. In the next, numerical computations obtained with nonlinear finite element code are presented. The model features the state-of-the-art in nonlinear fracture mechanics modeling and it is shown how the heterogeneous structure of concrete can be modeled via spatially varying parameters of the constitutive law. The crack growth in concrete induced by corrosion of steel reinforcement is modeled with the crack band model combined with a suitable damage law. Finally, the results of the analytical studies and numerical studies are compared and the paper concludes with a real-life numerical example.
