Long-Range Stress Redistribution Resulting From Damage in Heterogeneous Media [PDF]
, 2004 It has been shown in CA simulations and data analysis of earthquakes that declustered or characteristic large earthquakes may occur with long-range stress redistribution.

Rectification and Non-Gaussian Diffusion in Heterogeneous Media
Entropy, 2016 We show that when Brownian motion takes place in a heterogeneous medium, the presence of local forces and transport coefficients leads to deviations from a Gaussian probability distribution that make that the ratio between forward and backward ...

Nonlinear Poisson equation for heterogeneous media. [PDF]
Biophys J, 2012 The Poisson equation is a widely accepted model for electrostatic analysis. However, the Poisson equation is derived based on electric polarizations in a linear, isotropic, and homogeneous dielectric medium. This article introduces a nonlinear Poisson equation to take into consideration of hyperpolarization effects due to intensive charges and possible

A two-pressure model for slightly compressible single phase flow in bi-structured porous media [PDF]
, 2012 Problems involving flow in porous media are ubiquitous in many natural and engineered systems. Mathematical modeling of such systems often relies on homogenization of pore-scale equations and macroscale continuum descriptions.

Equivalence between volume averaging and moments matching techniques for mass transport models in porous media. [PDF]
, 2010 This paper deals with local non-equilibrium models for mass transport in dual-phase and dual-region porous media. The first contribution of this study is to formally prove that the time-asymptotic moments matching method applied to two-equation models is

Hydrodynamics of a Granular Gas in a Heterogeneous Environment
Entropy, 2017 We analyze the transport properties of a low density ensemble of identical macroscopic particles immersed in an active fluid. The particles are modeled as inelastic hard spheres (granular gas).

Nonlocal peridynamic method for porous media seepage simulation
Rock and Soil Mechanics, 2021 Based on the establishment of peridynamic nonlocal porous media seepage model, several kernel functions reflecting the degree of nonlocal effect are introduced to improve the calculation accuracy, and the peridynamic permeability coefficients ...

Homogenization and Field Concentrations in Heterogeneous Media [PDF]
SIAM Journal on Mathematical Analysis, 2006 A multi-scale characterization of the field concentrations inside composite and polycrystalline media is developed. The analysis focuses on gradient fields associated with the intensive quantities given by the temperature and the electric potential. In the linear regime these quantities are modeled by the solution of a second order elliptic partial ...
