Influence of nonlocal on a rotating thermoelastic medium with diffusion and double porosity [PDF]

open access: yesScientific Reports
In this paper, we have studied the thermodynamical interactions in a two-dimensional thermoelastic diffusion in homogeneous isotropic medium with nonlocal, rotation and double porosity in the context of Green–Lindsay theory. A thermal load was applied to

Non-simple elastic materials with double porosity structure

open access: yesArchives of Mechanics, 2022
This paper is concerned with a strain gradient theory of elastic materials that have a double porosity structure. Firstly, we present the basic equations and the boundary conditions of the nonlinear theory.

Research of the Behavior of Clay Materials with Double Porosity [PDF]

open access: yesSustainability, 2021
This contribution presents results from a series of compression and undrained triaxial tests to study the mechanical behavior of dump clay from the north of Bohemia. The use of these materials as a foundation for construction can’t be achieved without the adoption of some precautions.

Microstructure and Pore Characteristics of a SUS316L Gas Filter Fabricated by Wet Powder Spraying [PDF]

open access: yesArchives of Metallurgy and Materials, 2022
In this study, a flake-shaped metal powder was coated on a tube shaped pre-sintered 316L stainless steel support using a wet powder spraying process to fabricate a double pore structure, and the pore characteristics were analyzed according to coating ...

Sedimentation–consolidation of a double porosity material [PDF]

open access: yesComputers and Geotechnics, 2007
This paper studies the sedimentation-consolidation of a double porosity material, such as lumpy clay. Large displacements and finite strains are accounted for in a multidimensional setting. Fundamental equations are derived using a phenomenological approach and non-equilibrium thermodynamics, as set out by Coussy [Coussy, Poromechanics, Wiley ...

On the uniqueness and analyticity in viscoelasticity with double porosity [PDF]

open access: yesAsymptotic Analysis, 2019
In this paper we analyze the system of equations that models the behaviour of materials with a double porous structure. We introduce dissipation mechanisms in both structures. We show existence, uniqueness and analyticity for the solutions of the system.

Fluid Discrimination in Ultra-Deep Reservoirs Based on a Double Double-Porosity Theory

open access: yesFrontiers in Earth Science, 2021
We develop a methodology, based on rock-physics templates, to effectively identify reservoir fluids in ultra-deep reservoirs, where the poroelasticity model is based on the double double-porosity theory.

Modelling a hydration and heating column test on unsaturated bentonite using a double-porosity approach [PDF]

open access: yesE3S Web of Conferences, 2023
A controlled re-saturation of a heated 50 cm long column made of MX-80 bentonite pellets in the CIEMAT laboratory facilities (Madrid, Spain) has been running for 10 years (2011-2021).
