RÉSUMÉ

An approach to modeling processes of deformation of materials containing pores of diff erent sizes: from macroscopic pores with the diameter of several hundreds of microns or several millimeters to micropores of several hundreds of nanometers is presented. Diff erent solid mechanics body are used to investigate the stress-strain state of materials at diff erent scale levels of the microstructure. The multipole expansion method is used to describe deformation of the medium, containing macro-sized pores. A model of the Aero–Kuvshinsky quasi-continuum for porous media is used to estimate the distribution of the micropores in the medium. The problem on the isolated micro-sized spherical pore is solved within the framework of the gradient elasticity theory. Such solution makes it possible to verify the medium stress-strain state in the region of the micropore, depending on its size. Moreover, this solution can be used to show the range of pore sizes, for which the solution of the classical elasticity theory is valid.
