Compute part of the left-hand side.

Computes the linearisation of the material component with respect to a variation of material coordinates \((\Delta\mathbf{X})\):

\[ \textrm{D} \delta W^\text{(face)}_{\mathbf{t}}(\mathbf{x}, \mathbf{X}, \delta\mathbf{x}) [\Delta\mathbf{X}] = -\int\limits_{\mathcal{T}_{\xi}} \, \dfrac{\left\{\mathbf{F}^{\intercal}\cdot \mathbf{t} \right\} \cdot \delta\mathbf{x}}{\left\|\frac{\partial\mathbf{X}}{\partial\xi}\times\frac{\partial \mathbf{X}} {\partial\eta} \right\|} \left[ \frac{\partial\mathbf{X}} {\partial\xi} \cdot \left(\frac{\partial\Delta \mathbf{X}}{\partial\eta}\times\mathbf{N}\right) -\frac{\partial\mathbf{X}} {\partial\eta} \cdot \left(\frac{\partial\Delta \mathbf{X}}{\partial\xi}\times \mathbf{N}\right)\right] \textrm{d}\xi\textrm{d}\eta \]
