abstract = {The representative volume element (RVE) is a basic concept
in the continuum mechanics of sintering of random
heterogeneous porous materials. A quantitative determination
of its size was performed by using synchrotron X-ray
microtomography data of constrained sintering of thin glass
film on a rigid substrate. A RVE size is associated with a
property of interest; we determined it for relative density,
specific surface area, and hydrostatic component of
sintering stress. The RVE size was estimated to be from 11
to 17 times larger than the average initial particle size.
The RVE size was associated with a given precision of the
property. It depended on the volume fraction of porous
structure, or, relative density, so that it varied with
microstructural evolution.},
