In the theory of composite materials, the representative elementary volume (REV) (also called the representative volume element (RVE) or the unit cell) is the smallest volume over which a measurement can be made that will yield a value representative of the whole. In the case of periodic materials, one simply chooses a periodic unit cell (which, however, may be non-unique), but in random media, the situation is much more complicated. For volumes smaller than the RVE, a representative property cannot be defined and the continuum description of the material involves Statistical Volume Element (SVE) and random fields. The property of interest can include mechanical properties such as elastic moduli, hydrogeological properties, electromagnetic properties, thermal properties, and other averaged

  • O conceito de volume elementar representativo (VER ou REV na língua inglesa: Representative Elementary Volume) é muito utilizado no estudo de materiais porosos. Existe também a aplicação deste conceito em outras áreas, tais como propriedades mecânicas ou eletromagnéticas de alguns materiais. No texto que segue será utilizada a abreviatura REV, pois a abreviatura VER dá a impressão que trata-se de uma referência ao verbo "ver". (pt)

  • Two possible RVEs of a random composite. The RVE on the left is smaller than the one on the right. The distribution of particle sizes is identical in both RVEs.
  • Three-dimensional representative volume elements for monodisperse and polydisperse random composites.
  • Negative index metamaterial array configuration, which was constructed of copper split-ring resonators and wires mounted on interlocking sheets of fiberglass circuit board.
