Jun 17, 2009 · 2. Constitutive equations The conservation law (1.2) is not a closed equation for the density u. Typically, we supplement it with constitutive equations that relate the ux ~qand the source density ˙to uand its derivatives. While the conservation law expresses a gen-eral physical principle, constitutive equations describe the response of a ...
