Compute left-hand side.

Computes linearisation of the spatial component with respect to material coordinates.

Virtual work of the surface force corresponding to a test function of the spatial configuration \((\delta\mathbf{x})\):

\[ \delta W^\text{spatial}_{\mathbf t}(\mathbf{X}, \delta\mathbf{x}) = \int\limits_\mathcal{T} \mathbf{t}(\mathbf{X}) \cdot \delta\mathbf{x}\, \textrm{d}\mathcal{T} = \int\limits_{\mathcal{T}_{\xi}} \mathbf{t} \cdot \delta\mathbf{x} \left\| \frac{\partial\mathbf{X}}{\partial\xi}\times\frac{\partial \mathbf{X}} {\partial\eta} \right\| \, \textrm{d}\xi\textrm{d}\eta, \]

where \(\mathbf{t}\) is the force vector, \( \left\| \frac{\partial\mathbf{X}}{\partial\xi}\times\frac{\partial \mathbf{X}} {\partial\eta} \right\|\) is the length of the normal to the face in the material configuration, i.e. \(\|\mathbf{N}\|\) since \(\mathbf{N} = \frac{\partial\mathbf{X}}{\partial\xi}\times\frac{\partial \mathbf{X}} {\partial\eta}\) and \(\xi, \eta\) are coordinates in the parent space \((\mathcal{T}_\xi)\).

Linearisation with respect to a variation of material coordinates \((\Delta\mathbf{X})\):

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