Abstract

The paper deals with solution of the numerical simulation problem on the stress and strain concentration tensor components in mesoporous silicon-based structures with adsorbed water frozen under spatial constraints. The constructed model takes into account the presence of a natural layer of silicon dioxide on the surface of the pores in the studied materials, the structure of the inhomogeneous medium (the ratio of the oxide layer thickness to the radius of the filamentous pore, as well as the orientation of the pores in the space of the silicon membrane), and the volume content of the components.
