Definition

quantity representing the spatial distribution of mass of a continuous material:

$ρ (r) = \frac{d m}{d V}$

where $m$ is mass of the material contained in an infinitesimal domain at point $r$ and $V$ is volume of this domain

grandeur représentant la répartition spatiale de la masse d'un matériau continu :

$ρ (r) = \frac{d m}{d V}$

où $m$ est la masse du matériau contenue dans un domaine infinitésimal au point $r$ et $V$ est le volume de ce domaine
