Magma convection favors ephemeral melt-rich bodies within mushy reservoirs [PDF]

open access: yesNature Communications
Magma convection is a mechanism that greatly enhances heat transfer from mobilizable, crystal-poor magma bodies to the surrounding immobile, crystal-rich mush reservoir of Earth’s igneous systems.

Design of sound absorbers based on open-cell foams via microstructure-based modeling [PDF]

open access: yesArchives of Acoustics, 2022
Effects of microstructure factors on the acoustic performance of open-cell foams can be characterized numerically by a microstructure-based approach. To this regard, the numerical homogenization approach and the equivalent-fluid theory are employed to ...

Local numerical homogenization in modeling of heterogeneous visco-elastic materials [PDF]

open access: yesComputer Methods in Materials Science, 2013
The main objective of this paper is to present the prospects of application of local numerical homogenization to visco-elastic problems. Local numerical homogenization is one of the computational homogenization methods, proposed by Jhurani in 2009 for ...

Parallel evolutionary optimization in multiscale problems [PDF]

open access: yesComputer Methods in Materials Science, 2009
The paper is devoted to optimization in multiscale problems. The composite modelled as a macrostructure with a local periodic microstructure is considered. The multiscale analysis is performed with the use of the homogenization method.

Homogenization modelling of antibiotic diffusion and adsorption in viral liquid crystals

open access: yesRoyal Society Open Science, 2023
Systems of rod-shaped viruses have long been important to the science of living liquid crystals, as their monodispersity and uniform charge make them convenient model systems. Recently, it was shown that, upon the addition of polymers, suspensions of rod-

Numerical homogenization method in the modeling of gas hydrate bearing sediments [PDF]

open access: yesE3S Web of Conferences, 2020
The study of the mechanical behavior of gas hydrate bearing soils represents a major interest. The hydrate inclusions in sediments change their microstructure and their mechanical properties with it.

Effective behavior of long and short fiber-reinforced viscoelastic composites

open access: yesApplications in Engineering Science, 2021
We study the homogenized properties of linear viscoelastic composite materials in three dimensions. The composites are assumed to be constituted by a non-aging, isotropic viscoelastic matrix reinforced by square or hexagonal arrangements of elastic ...

Numerical Investigation on Effective Elastic Modulus of Multifractal Porous Materials

open access: yesFractal and Fractional, 2022
The design of a novel material necessitates a fundamental understanding of its structure–property relation. Inorganic porous materials (media) such as natural soil and rock, and artificial ceramic and cement, exhibit multifractal characteristics in view ...
