Abstract
This chapter represents the formulation of generic balances for generic volume as well as surface and curve extensive quantities, thereby highlighting their global and local formats and resorting in both cases to material and spatial control volumes as well as control surfaces and control curves.

Notes
- 1.
The intrinsic flux \({\boldsymbol{Z}}\) is related to the material configuration and the material time derivative of the balanced quantity \({\boldsymbol{z}}_\mathrm{m}\). The dynamic flux \({\boldsymbol{Z}}+{\boldsymbol{z}}_\mathrm{m}\otimes {\boldsymbol{W}}\) may be considered as a (right-sided referential\(\rightarrow \)material) Piola transformation of a corresponding flux \(\pmb {\mathcal{{Z}}}\) as related to the reference configuration and the total time derivative of the balanced quantity \({\boldsymbol{z}}_\mathrm{r}\). The latter denotes a density per unit volume in the reference configuration. The referential perspective on continuum mechanics is elaborated in much more detail within Chaps. 9 and 10 on Virtual Work and the Variational Setting, respectively.
