TL;DR: In this paper, the authors provided micromorphic modeling of a granular material in a macroelement and at a macroscopic point, using the discrete-continuum correspondence for these field quantities.

TL;DR: In this paper, the fluid dynamic behavior within a pixel of an electrowetting display (EWD) is thoroughly investigated through a 3D simulation through coupling the electrohydrodynamic (EHD) force deduced from the Maxwell stress tensor with the laminar phase field of the oil-water dual phase.

TL;DR: In this paper, a continuum thermodynamic theory for the analysis of reversible and irreversible compaction of cohesionless granular particles when a vertical oscillation is exerted on the system is proposed.

Abstract: This paper models a microcontinuum as a mixture with continuous diversity.Balance equations for a microcontinuous medium are discussed from theviewpoint of mesoscopic continuum mechanics. The macroscopic field quan-tities are redefined in terms of the mesoscopic averages rather than by takingspatial averages in a macroelement. The averages of the mesoscopic balanceequations of mass, linear momentum, angular momentum, and energy pro-duce their macroscopic counterparts. With the mixture formulation, the ki-netic fluxes, which are missing in the derivations by other macroscopicapproaches, are naturally incorporated into the stress tensor, couple stresstensor, and heat flux. For a microcontinuum, the balance equation of micro-inertia is the second-moment equation for the mesoscopic balance of mass.Introducing the mesoscopic distribution function can produce the explicit ex-pression for the general macroscopic n-th moment equation. 1. Introduction Rapid advances in material science and technology have encouraged re-searchers and scientists to study and use materials with internal structures.Apparently, internal degrees of freedom usually characterize materials suchas liquid crystals, polymers, polycrystals, macromolecular solutions, etc. Themacroscopic microcontinuum (a continuum with internal structures) fieldtheory constructed by Eringen and Suhubi [1] and Eringen [2] is an excellent

TL;DR: In this paper, the Lagrangian-to-Eulerian transformation approach is used to construct noncanonical Poisson brackets for the conservative part of elastic solids and micromorphic elastic solutions.
