... hexagonal structures having a negative Poisson’s ratio shows a high macroscopic shear flexible property associated with the high h when the honeycombs are designed to have the same macroscopic shear modulus. The simple shear deformation of hexagonal honeycombs is simulated within a constituent material’s...

... 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. The present investigation...
