The dual variational formulation of the problem of linear elasticity of the porous non-
homogeneous solid body consisting of the chaotically directed isotropic fragments with
different elastic characteristics is used for constructing the two-way estimates of the ef-
fective elastic behaviour of such body. We have conducted the quantitative analysis of
these estimates and compared them with the known previously published results. The pre-
sented calculated ratios can be applied for forecasting the effective values of elasticity
moduli of the porous composite material reinforced with isotropic inclusions as well as
the materials obtained by means of powder metallurgical techniques and self-
propagating high-temperature synthesis.
Keywords:
porous solid body, effective values of the elasticity moduli, dual variational
formulation, two-way estimates
