Method for computing plane stress stiffness matrix of receiver.

Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to plane stress stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix.

Parameters
answerStiffness matrix.
mmodeMaterial response mode.
gpIntegration point, which load history is used.
tStepTime step (most models are able to respond only when tStep is current time step).

Computes the stiffness matrix for giveRealStressVector of receiver in given integration point, respecting its history.

The algorithm should use temporary or equilibrium history variables stored in integration point status to compute and return required result.

Parameters
answerContains result.
modeMaterial response mode.
gpIntegration point.
tStepTime step (most models are able to respond only when tStep is current time step).
