Why Effective Medium Theory Fails in Granular Materials
Experimentally it is known that the bulk modulus K and shear modulus m of a granular assembly of elastic spheres increase with pressure p faster than the p1 3 law predicted by effective medium theory (EMT) based on Hertz-Mindlin contact forces. To understand the origin of these discrepancies, we perform numerical simulations of granular aggregates under compression. We show that EMT can describ...
متن کاملThe Apparent Failure of Effective Medium Theory in Granular Materials
The linear and nonlinear elastic properties of granular media are analyzed within the context of effective medium theories, as well as with numerical molecular dynamic simulations, assuming the validity of the Hertz-Mindlin theory at the single contact level. Them is a crucial distinction between force laws which are path independent, leading to a hyper-elastic effective medium theory, and thos...
متن کاملTerahertz scattering by granular composite materials: An effective medium theory
Terahertz (THz) spectroscopy and imaging have emerged as important tools for identification and classification of various substances, which exhibit absorption characteristics at distinct frequencies in the THz range. The spectral fingerprints can potentially be distorted or obscured by electromagnetic scattering caused by the granular nature of some substances. In this paper, we present THz tim...
متن کاملEffective medium theory of left-handed materials.
We analyze the transmission and reflection data obtained through transfer matrix calculations on metamaterials of finite lengths, to determine their effective permittivity epsilon and permeability micro. Our study concerns metamaterial structures composed of periodic arrangements of wires, cut wires, split ring resonators (SRRs), closed SRRs, and both wires and SRRs. We find that the SRRs have ...
متن کاملGeneralized Effective Medium Theory for Particulate Nanocomposite Materials
The thermal conductivity of particulate nanocomposites is strongly dependent on the size, shape, orientation and dispersion uniformity of the inclusions. To correctly estimate the effective thermal conductivity of the nanocomposite, all these factors should be included in the prediction model. In this paper, the formulation of a generalized effective medium theory for the determination of the e...
