Conclusions

Using a model of plastic flow of porous solids proposed in [1], expressions have been derived with the aid of which it is possible to determine the porosity and geometric dimensions of a cylindrical specimen subjected to hydromechanical compression with a constant lateral pressure and in a closed volume of liquid. To attain the maximum specimen density, deformation should be performed at the lowest possible lateral pressure which does not yet lead to the rupture of the specimen.
