| 101 Lattice Based Thermodynamics & Diffusion Module The Lattice Based Thermodynamics & Diffusion Module deals with (multicomponent) chemical potential and solubility in different material layers as function of temperature, system pressure and stress on the element under consideration. The module also seamlessly calculates (multicomponent) diffusion rates. On this basis, permeation rate, time lag, degree of plasticizing and material expansion are determined. Effects of (anomalous) ageing are included. |

| 102 Surface & Chemical Activity Driven Corrosion Module The Surface & Chemical Activity Corrosion Module quantifies surface corrosion phenomena and chemical activity (fugacity) driven degradation of internal interfaces, like fillers and reinforcements. Since the long term strength of combined materials is largely dependent on interfacial robustness, this module is vital in many circumstances. Effects of UV and Cathodic Protection are included. |

| 103 Gibbs Free Restraint Module The Gibbs Free Restraint Module is based on a thermodynamical-mechanical fracture analysis of material components and interfaces between individual components. The module predicts whether surfaces will restrain effects of a local stress potential and local chemical degradation. If restraint as function of place and time is insufficient, the module predicts the extent of fracture/ageing. |
