An experimental model for studying the effect of anisotropy on percolative conduction
نویسندگان
چکیده
2014 We present preliminary measurements of the electrical conductivity of a composite made of small conducting rods in an insulating matrix. It constitutes a model material for studying the effect of anisotropy on percolation as a function of particle length to diameter ratio. We can interpret our results, especially the lowering of threshold respective to isotropic systems, by means of a geometrical argument when the ratio is high as in our experiments. J.

Studying the effect of inherent anisotropy on undrained behavior of sand-silt mixtures
In some situations, dams need to be built on non-rock alluvial grounds such as sand and sand-silt deposits. Therefore, undrained behavior and strength of silty sands are of great importance. One of the critical factors in studying the behavior of sand-silt mixtures is inherent anisotropy, a natural soil characteristic that depends on its texture and is independent of the soil's initial stress s...
متن کاملAnisotropic Thermal Properties of Solid Polymers
This paper discusses the thermal conduction anisotropy in polymers by reviewing currently available theories and experimental methods for studying oriented polymers. The anisotropic thermal conductivity and diffusivity of oriented polymers originate from the difference between the thermal energy transport mechanisms parallel and perpendicular to their molecules. Recent progress in the developme...
متن کاملFinite element simulation of the clinching process of steel sheets and study on influence of anisotropy on the mechanical behavior of joint
This article describes a numerical study on the TOX-clinching process of the steel sheets. In addition, the influence of plastic anisotropy of the material on joining parameters is analyzed by evolution of the joint parameters such as undercut and neck thickness and punch force-displacement curve. Finite element analysis with ABAQUS/CAE-Explicit program is used to simulate two dimensional and t...
متن کاملAn Experimental Model for Studying Atherosclerosis
The aim of the present study was to clarify if old N-MRI rat, a strain which is easily available in Iran and cheap to maintain, is a suitable alternative to those previously reported. In this model, we compared three quantifiable parameters between old and young rats: biochemically, involving measurement of differences in the lipid profile. Histologically, the differences of the thickness of th...
متن کاملStudy Of Thermoelastic Damping in an Electrostatically Deflected Circular Micro-Plate Using Hyperbolic Heat Conduction Model
Thermoelastic damping (TED) in a circular micro-plate resonator subjected to an electrostatic pressure is studied. The coupled thermo-elastic equations of a capacitive circular micro plate are derived considering hyperbolic heat conduction model and solved by applying Galerkin discretization method. Applying complex-frequency approach to the coupled thermo-elastic equations, TED is obtained for...
