Abstract

An electrochemical and mechanical modeling approach to simulate formation of corrosion in- duced cracks in reinforced concrete structures is presented. The electrochemical model allows simulation of the propagation of macro cell corrosion in a homogeneous defect-free concrete-steel system. To simulate cracking a finite element based crack propagation model is proposed. To demonstrate the potential use of the combined modeling approach a numerical example is provided where the influence of various exposure con- ditions on the corrosion current density and subsequent formation of cracks is illustrated.
