Bulk strain energy density in por-Si – H2O structures near the phase transition point of water

The problem of modeling the bulk strain energy density in mesoporous siliconbased structures with adsorbed water frozen under conditions of spatial limitation (confinement) is solved. The model takes into account the presence of a silicon dioxide layer on the pore surfaces of the mesoporous material, the structure of the inhomogeneous medium, and the volume fractions of the components. Numerical calculations of the values of the indicated energy characteristics from changes in the volumetric ice content in the materials under study were carried out.
