In the field of civil engineering, the cracks propagation in concrete is predominantly influenced by temperature fluctuations, moisture content, corrosion, and mechanical stresses. Engineers must then determine whether to repair or demolish the structure, contingent on the extent of the damage. However, replacing such damaged structures can rapidly become financially exorbitant and, in certain instances, may compromise safety. To extend the service life of these structures, the use of new materials, such as carbon fiber (CF) and fiber-reinforced polymer (FRP) has been proposed due to their corrosion resistance, low density, and high mechanical properties. Usually, the rehabilitation of damaged structures is followed by numerical analysis to simulate crack propagation, quantify physical damage and sometimes to evaluating the remaining lifetime. In this work, a numerical analysis has been carried out using a constitutive inelastic damage model coupled with orthotropic materials, such as CF or and FRP. The numerical tool called SiCaR has been developed using the foam-extend-5.0 open-source code, which is available in the literature. The constitutive inelastic-damage model is used to simulate the multimaterial degradation coupled with thermal and humidity effects.
