void oofem::StructuralInterfaceElementPhF::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep
	)

virtual

Computes the stiffness/tangent matrix of receiver.

Default implementation computes element stiffness using $K=\int_{\Gamma} N^{\mathrm{T}} D N \mathrm{d}V$ formulae, where $ N $ is the element geometric matrix such that $ j = N a $ and $ D $ is the stiffness matrix of the interface material. Numerical integration procedure uses integrationRulesArray for numerical integration.

The geometrical matrix is obtained using computeNmatrixAt service and the constitutive matrix is obtained using computeConstitutiveMatrixAt service.

For higher numerical performance, only one half of stiffness matrix is computed and answer is then symmetrized. Therefore, if element matrix will be generally nonsymmetric, one must specialize this method. Finally, the result is transformed into global coordinate system (or nodal coordinate system, if it is defined).

Parameters

answer	Computed stiffness matrix (symmetric).
rMode	Response mode.
tStep	Time step.

Todo:: this part is enough to do once

void oofem::StructuralInterfaceElementPhF::giveInternalForcesVector	(	FloatArray &	answer,
		TimeStep *	tStep,

	)

virtual

Returns equivalent nodal forces vectors.

Useful for nonlinear analysis. Default implementation computes result as $F=\int_v B^{\mathrm{T}} \sigma \mathrm{d}V$ , where $\sigma$ is the real element stress vector obtained using computeStressVector service (if useUpdatedGpRecord=0) or (if useUpdatedGpRecord=1) from integration point status. The geometric matrix is obtained using computeBmatrixAt service. Integration is performed using default integration rule, which should produce always valid results, assuming that strains used for computation of stresses are valid.

Parameters

answer	Internal nodal forces vector.
tStep	Time step.
useUpdatedGpRecord	If equal to zero, the stresses in integration points are computed (slow but safe), else if nonzero the stresses are taken directly from integration point status (should be derived from StructuralMaterialStatus) (fast, but engineering model must ensure valid status data in each integration point).

void oofem::StructuralInterfaceElementPhF::updateInternalState ( TimeStep * tStep )

virtual

Updates element state after equilibrium in time step has been reached.

Default implementation updates all integration rules defined by integrationRulesArray member variable. Doing this, all integration points and their material statuses are updated also. All temporary history variables, which now describe equilibrium state are copied into equilibrium ones. The existing internal state is used for update.

Parameters

tStep Time step for newly reached state.
