... concerning the electric characterization of random mixtures have been drawn. The specific analysis of porous random materials has been performed and largely discussed. Such an analysis leads to the evaluation of the percolation threshold, to the determination of the convergence properties of Poisson’s ratio...

... energy density function. The parameters of the model were determined by fitting the available from the literature uniaxial tension experimental data with the constitutive equation derived from the M/R model. The optimum value of the Poisson ratio is adjusted by comparing the experimentally observed...

... preform densities. Further it was found that the preforms of higher iron content shows higher values of deformation properties like the axial stress and the Poisson’s ratio than less/without iron preforms provided that the initial fractional density taken is kept constant. During the elastic deformation...

.... The adopted method is based on two assumptions: the first one assumes that each grain has the same elastic properties as the aggregate, i.e., the granular Lame’s coefficients (λ and μ) are equal to their macroscopic ones. Thus, they are computed from the overall Young’s modulus and the Poisson’s ratio using...
