"Rodney Hill defined the RVE as a sample of a heterogeneous material that: 1. "is entirely typical of the whole mixture on average”, and 2. "contains a sufficient number of inclusions for the apparent properties to be independent of the surface values of traction and displacement, so long as these values are macroscopically uniform.” " - Rve homogenization

Webdomain Ω is what we call homogenization. There is a diﬀerence of methodology between the traditional physical approach of homogenization and the mathematical theory of homogenization. In the mechanical lit-erature, the so-called representative volume element (RVE) method is often used (see [8], or Chapter 1 in [17]). WebDec 7, 2024 · A widespread convention is to define the RVE as the smallest repeating unit cells. In this contribution different sizes of an RVE will be analysed, i.e. RVEs with different numbers of unit cells.
