Abstract:
This work outlines the theoretical model based on the theory of multicomponent media allowing for description of elasto-plastic electrochemical corrosion degradation with diffusion in the reinforced concrete structures. The form of the Helmholtz free energy is presented as a function of degradation parameter and part of elastic, plastic and diffusion energies. The description of degradation parameters and their evolution is also proposed here. The strong and weak boundary value problem and the linearized form of boundary value problem have been formulated in the form convenient for computer implementation. Finally, the exemplary analysis is performed.
