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

Non-Local Sensitivity Analysis and Numerical Homogenization in Optimal Design of Single-Wall Corrugated Board Packaging [PDF]
The optimal selection of the composition of corrugated cardboard dedicated to specific packaging structures is not an easy task. The use of lighter boards saves material, but at the same time increases the risk of not meeting the guaranteed load capacity.

An Elliptic Local Problem with Exponential Decay of the Resonance Error for Numerical Homogenization
Numerical multiscale methods usually rely on some coupling between a macroscopic and a microscopic model. The macroscopic model is incomplete as effective quantities, such as the homogenized material coefficients or fluxes, are missing in the model. These effective data need to be computed by running local microscale simulations followed by a local ...

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

A parabolic local problem with exponential decay of the resonance error for numerical homogenization [PDF]
This paper aims at an accurate and efficient computation of effective quantities, e.g. the homogenized coefficients for approximating the solutions to partial differential equations with oscillatory coefficients. Typical multiscale methods are based on a micro–macro-coupling, where the macromodel describes the coarse scale behavior, and the micromodel

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

Homogenization modelling of antibiotic diffusion and adsorption in viral liquid crystals
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-
