Method Detail

computeStress

void computeStress(SymmetricMatrix3d sigma,
                   SolidDeformation def,
                   IntegrationPoint3d pt,
                   IntegrationData3d dt,
                   FemMaterial baseMat)

computeTangent

void computeTangent(Matrix6d D,
                    SymmetricMatrix3d stress,
                    SolidDeformation def,
                    IntegrationPoint3d pt,
                    IntegrationData3d dt,
                    FemMaterial baseMat)

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
