Method Detail

computeStressAndTangent

void computeStressAndTangent(SymmetricMatrix3d sigma,
                             Matrix6d D,
                             DeformedPoint def,
                             IntegrationPoint3d pt,
                             IntegrationData3d dt,
                             MaterialStateObject state)

computeStrainEnergyDensity

double computeStrainEnergyDensity(DeformedPoint def,
                                  IntegrationPoint3d pt,
                                  IntegrationData3d dt,
                                  MaterialStateObject state)

hasSymmetricTangent

boolean hasSymmetricTangent()

isInvertible

boolean isInvertible()

isLinear

boolean isLinear()

Linear stress/stiffness response to deformation, allows tangent to be pre-computed and stored.

Returns:

true if linear response

isCorotated

boolean isCorotated()

Deformation is computed by first removing a rotation component (either explicit or computed from strain)

Returns:

true if material is corotated

hasState

default boolean hasState()

Specified by:

hasState in interface HasMaterialState

createStateObject

default MaterialStateObject createStateObject()

Specified by:

createStateObject in interface HasMaterialState
