Multiscale and multiphysics modelling for sustainable materials

Porous carbon-based adsorption materials have been found to be very useful in methane adsorption, storage, and transportation but they could undergo enzymatic and chemical degradation up to fracture, hence a Poro-Mechanics Model (PMM) is upgraded to take into account damage in finite strains. When accounting for high-purity hydrogen production, the Proton Exchange Membrane Water Electrolysis (PEMWE) stands out as a promising technology offering a carbon-neutral energy source, so that the PMM is extended to account for dissolved solutes or mobile ions, including proton diffusion driven by concentration and electric potential gradients. If facing nuclear shielding hazards or External Sulphate Attack (ESA), a meso scale modeling of cementitious materials is necessary, as well as the adoption of Industrial Tomography and/or random distribution algorithms to numerically generate grading curves consistent with material mix designs. Additionally, the constitutive characterization of the porous medium must be deepened even more to account for e.g. creep, temperature and chemical reactions. When including structural steel and varying loading conditions, a Fatigue SS (FSS) model is to be adopted, demonstrating advantages over conventional elastoplastic theories.
