computeStressAndTangent

public void computeStressAndTangent(SymmetricMatrix3d sigma,
                                    Matrix6d D,
                                    DeformedPoint def,
                                    Vector3d dir0,
                                    double excitation,
                                    MaterialStateObject state)

Specified by:

computeStressAndTangent in class MuscleMaterial

computeStrainEnergyDensity

public double computeStrainEnergyDensity(DeformedPoint def,
                                         Vector3d dir0,
                                         double excitation,
                                         MaterialStateObject state)

Specified by:

computeStrainEnergyDensity in class MuscleMaterial

equals

public boolean equals(MuscleMaterial mat)

Overrides:

equals in class MuscleMaterial

isInvertible

public boolean isInvertible()

Description copied from class: MuscleMaterial

Returns true if this material is defined for a deformation gradient with a non-positive determinant.

Overrides:

isInvertible in class MuscleMaterial

clone

public InactiveMuscle clone()

Description copied from interface: CompositeProperty

Returns a clone of this composite property.

Specified by:

clone in interface CompositeProperty

Specified by:

clone in interface Clonable

Overrides:

clone in class MuscleMaterial

Returns:

clone of this property

isThreadSafe

public boolean isThreadSafe()

Description copied from class: FemMaterial

Queries whether this material's stress, tangent and energy methods can be called concurrently from multiple threads (for different deformed points). This requires that the methods do not modify any shared internal state. The default implementation returns false; subclasses which are thread safe should override this. If the material has properties bound to fields (see FemMaterial.collectFieldBindings(java.util.List<artisynth.core.modelbase.FieldComponent>)), then concurrent use additionally requires that FieldComponent.updateForConcurrentAccess() has been called for each of those fields.

Overrides:

isThreadSafe in class FemMaterial

Returns:

true if this material is thread safe
