◆ doWork()

MoFEMErrorCode SimpleContactProblem::OpCalContactAugmentedTractionOverSpatialMasterMaster::doWork ( int  row_side,
int  col_side,
EntityType  row_type,
EntityType  col_type,
EntitiesFieldData::EntData row_data,
EntitiesFieldData::EntData col_data 
)

Integrates virtual work on master side , \( \delta W_{\text c}\), derivative with respect to spatial positions of the master side and assembles its components to LHS global matrix.

Computes linearisation of integrated on slave side complementarity function and assembles Lagrange multipliers virtual work \( \delta W_{\text c}\) on master side with respect to spatial positions of the master side and assembles components to LHS global matrix

\[ {\text D} {\delta W^{(2)}_{\text c}(\lambda, \delta \mathbf{x}^{(2)}})[\Delta {\mathbf{x}^{(2)}}] \,\, = \left\{ \begin{array}{ll} \int_{{\gamma}^{(1)}_{\text c}} c_{\textrm n}\Delta {\mathbf{x}^{(2)}} \cdot [{\mathbf{n}}_{\rm c} \otimes {\mathbf{n}}_{\rm c}] \cdot \delta{\mathbf{x}^{(2)}}\,\,{ {\text d} {\gamma}} & \lambda + c_{\text n} g_{\textrm{n}}\leq 0 \\ 0 & \lambda + c_{\text n} g_{\textrm{n}}> 0 \\ \end{array} \right. \]

where \({\gamma}^{(1)}_{\text c}\) is the surface integration domain of the slave surface, \( \lambda\) is the Lagrange multiplier, \(\mathbf{x}^{(2)}\) are the coordinates of the overlapping gauss points at master triangles, \( c_{\textrm n}\) is the regularisation/augmentation parameter of stress dimensions and \( g_{\textrm{n}}\) is the gap evaluated on the corresponding slave side.
