Definition of volume-specific variables. MPR, Mass Production Rate; SEF, Strain Energy Function; α = {e, m, c}, Γ = {M, A}.

Mass of constituent α within layer Γ per unit current volume of layer Γ	${\rho }_{\Gamma }^{\alpha }$
Mass of constituent α within layer Γ per unit reference volume of layer Γ	${\rho }_{\Gamma R}^{\alpha }$
MPR of constituent α within layer Γ per unit reference volume of layer Γ	$m_{\Gamma R}^{\alpha }$
Nominal MPR of constituent α within layer Γ per unit reference volume of layer Γ	$m_{\Gamma N}^{\alpha }$
Volume-specific SEF of constituent α (defined at the constitutive level)	${\widehat{W}}^{\alpha }$
SEF of constituent α within layer Γ per unit reference volume of layer Γ	$W_{\Gamma R}^{\alpha }$
