Abstract
On the basis of the analysis of correlation characteristics of locally-elastic properties of modeling material the task of definition of locally-representative volume at different parameters of porosity is solved. For the analysis of dispersity of pores modeling cellular structures with volume content of 55 % and bimodal system of pores were considered. There were selected accidentally the limits of with representative volume 300 points in which local elastic properties were investigated. For definition of these properties each point on mesoscopical representative volume (MRV) level is presented by a small fragment of modeling frame of a porous media, MRV with characteristic for it geometry of frame of pores. Calculation of elastic properties of each such MRV was carried out by a method of final elements with use of the equipment of calculation of parameters tensely-strained state at mesolevel and their data smoothing. It is revealed that the ratio between the maintenance of large and small pores in dispersible-porous medium plays an important role. The dependence of an effective elastic module on a share of a time of large pores is set.
