Transformation of tensors that are defined in terms of a set of contravariant bases. Rank-1 and rank-2 contravariant tensors \(\left(\bullet\right)^{\sharp} = \mathbf{T}\) (and its spatial counterpart \(\mathbf{t}\)) typically satisfy the relation
\[ \int_{V_{0}} \nabla_{0} \cdot \mathbf{T} \; dV = \int_{\partial V_{0}} \mathbf{T} \cdot \mathbf{N} \; dA = \int_{\partial V_{t}} \mathbf{T} \cdot \mathbf{n} \; da = \int_{V_{t}} \nabla \cdot \mathbf{t} \; dv \]
where \(V_{0}\) and \(V_{t}\) are respectively control volumes in the reference and spatial configurations, and their surfaces \(\partial V_{0}\) and \(\partial V_{t}\) have the outwards facing normals \(\mathbf{N}\) and \(\mathbf{n}\).
