This article explores the use of a homogenization method inspired by the classical Irving-Kirkwood procedure in the continuous multiscale modeling of elastic solids within the context of the finite element method. This homogenization method gives rise to a broad range of allowable boundary conditions for the RVE, which, in turn, yield a rich spectrum of estimates of the macroscopic stress respo...

In this paper we implement in hardware, a novel approach for accelerating the S-W algorithm using Recursive Variable Expansion (RVE) technique, which enhances inherent parallelism and exposes extra parallelism as compared to any other technique. The results demonstrate that applying recursive variable expansion technique speeds up the performance by a factor of 3.83, as compared to traditional ...

We analyze plane strain deformations of a representative volume element (RVE) to evaluate effective thermophysical parameters of a particulate composite comprised of two perfectly bonded heat conducting elasto-thermo-visco-plastic constituents. It is assumed that the composite is also isotropic and its response elasto-thermo-visco-plastic. Effective values of material parameters so computed are...

AIMS Microvascular endothelial barrier breakdown in sepsis precedes organ failure and death in patients. We tested the hypothesis that the formation of endothelium-derived soluble vascular endothelial (VE)-cadherin fragments (sVE-cadherin) is involved in inflammation-induced endothelial barrier disruption. METHODS AND RESULTS Incubation of human dermal microvascular endothelial cells (HDMEC) ...

The effect of the clusterization on effective properties a composite material reinforced by MXene or graphene platelets is studied using finite element method with periodic representative volume (RVE). A hybrid 2D/3D mesh used to reduce computational complexity numerical model. Several realizations an RVE were generated increasing fractions inclusions, resulting in progressive platelets. Numeri...

This paper presents a computational framework that generates ensemble predictive mechanics models with uncertainty quantification (UQ). We first develop causal discovery algorithm to infer relations among time-history data measured during each representative volume element (RVE) simulation through directed acyclic graph. With multiple plausible sets of relationships estimated from RVE simulatio...

prediction of mechanical properties of carbon nanotube-based composite is one of the important issues which should be addressed reasonably. a proper modeling approach is a multi-scale technique starting from nano scale and lasting to macro scale passing in-between scales of micro and meso. the main goal of this research is to develop a multi-scale modeling approach to extract mechanical propert...

The statistical significance of grain-scale lattice rotation results is analysed. case the Ref. [1] specifically considered. Quantitative elements theory statistics are applied to determine precisions (standard errors) and size representative volume element (RVE), in terms minimal number grains necessary obtain results. It shown that defined sufficient precision support conclusions made. In gen...
