REPRESENTATIVE VOLUME ELEMENT: A STATISTICAL POINT OF VIEW

摘要

The Representative Volume Element (RVE) plays a central role in the mechanics and physics of random heterogeneous materials, when predicting their effective properties. We propose a statistical approach of this notion, where a quantitative definition of the size of the RVE is derived from estimations of the effective properties, and of fluctuations of the fields on realizations of a random medium in a finite domain V.
