Scale transition and enforcement of RVE boundary conditions in second-order computational homogenization [PDF]

open access: yes, 2007
Formulation of the scale transition equations coupling the microscopic and macroscopic variables in the second-order computational homogenization of heterogeneous materials and the enforcement of generalized boundary conditions for the representative ...

Snowbeds are more affected than other subalpine–alpine plant communities by climate change in the Swiss Alps

open access: yesEcology and Evolution, 2016
While the upward shift of plant species has been observed on many alpine and nival summits, the reaction of the subalpine and lower alpine plant communities to the current warming and lower snow precipitation has been little investigated so far.

Changes in beta diversity and species functional traits differ between saplings and mature trees in an old‐growth forest

open access: yesEcology and Evolution, 2021
Invasion by generalist tree species can cause biotic homogenization, and such community impoverishment is likely more important in rare forest types. We quantified changes in tree diversity within Carolinian (range in Central Hardwood Forest), central ...

Mathematical homogenization of inelastic dissipative materials: a survey and recent progress [PDF]

open access: yes, 2017
In this paper, a review of papers on mathematical homogenization of dissipative composites under small strains and on the interplay between homogenization procedure and dissipation due to mechanical work is presented.

Subsampling and homogenization to investigate variability of composite material mechanical properties [PDF]

open access: yes, 2012
This paper presents an innovative homogenization sampling technique applied to multiscale modelling of composite materials. The goal is to build efficiently statistical variability of mechanical properties at mesoscopic scale from the heterogeneous media

Microstructural and Microhardness Evolution from Homogenization and Hot Isostatic Pressing on Selective Laser Melted Inconel 718: Structure, Texture, and Phases

open access: yesJournal of Manufacturing and Materials Processing, 2018
In this work, the microstructure, texture, phases, and microhardness of 45° printed (with respect to the build direction) homogenized, and hot isostatically pressed (HIP) cylindrical IN718 specimens are investigated.

Homogeneity and h -homogeneity

open access: yesTopology and its Applications, 2013
A topological space \(X\) is \textit{homogeneous} if each of its points can be carried to any other via a homeomorphism of the space; \(X\) is \textit{\(h\)-homogeneous} if it is homeomorphic to each of its nonempty clopen subspaces. The author investigates conditions under which these two notions are related for zero-dimensional spaces. The first main

Relative Homogenization of Climatic Time Series

open access: yesAtmosphere
Homogenization of the time series of observed climatic data aims to remove non-climatic biases caused by technical changes during the history of the climate observations.

Creep of a C-S-H gel: a micromechanical approach

open access: yesAnais da Academia Brasileira de Ciências, 2010
Both clays and calcium silicate hydrates(the main hydration products of Portland cements) exhibit a microstructure made up of lamellar particles. The microscopic mechanism responsible for the macroscopic creep of such materials is often described as the ...
