Summary In this paper a coupled thermodynamical/chemical/mechanical model is developed to simulate the time dependent degradation of heterogeneous solid materials subjected to corrosive environments. The model, which is based on a description of the microscale, employs the first law of thermodynamics, a mass balance of a diffusing corrosive species, and a balance of momentum. The presence of the corrosive species is phenomenologically modeled as irreversibly reducing the material stiffness, dependent on the amount and time present. Numerical experiments are given to illustrate some characteristics of the model.
