Method for computing 1d stiffness matrix of receiver.

Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to 1d 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).

void oofem::AnisotropicDamageMaterial::givePlaneStrainStiffMtrx ( FloatMatrix answer,

)
protectedvirtual

Method for computing plane strain stiffness matrix of receiver.

Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to plane strain 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. Note: as already described, if zero strain component is imposed (Plane strain, ..) this condition must be taken into account in geometrical relations, and corresponding component has to be included in reduced vector. (So plane strain conditions are $ \epsilon_z = \gamma_{xz} = \gamma_{yz} = 0 $, but relations for $ \epsilon_z$ and $\sigma_z$ are included).

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).

void oofem::AnisotropicDamageMaterial::giveRealStressVector ( FloatArray answer,
GaussPoint gp,
const FloatArray reducedStrain,
TimeStep tStep 
)
virtual

Computes the real stress vector for given total strain and integration point.

The total strain is defined as strain computed directly from displacement field at given time. The stress independent parts (temperature, eigenstrains) are subtracted in constitutive driver. The service should use previously reached equilibrium history variables. Also it should update temporary history variables in status according to newly reached state. The temporary history variables are moved into equilibrium ones after global structure equilibrium has been reached by iteration process.

Parameters
answerStress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress.
gpIntegration point.
reducedStrainStrain vector in reduced form. For large deformations it is treated as the Green-Lagrange strain.
tStepCurrent time step (most models are able to respond only when tStep is current time step).
Todo:
check if computeTraceD is necessary and check its implementation
Todo:
Move this to StructuralCrossSection ?
