Constructor Detail

AnisotropicLinearMaterial

public AnisotropicLinearMaterial()

Creates a new AnisotropicLinearMaterial with default (isotropic) parameter values.

AnisotropicLinearMaterial

public AnisotropicLinearMaterial(double E,
                                 double nu)

AnisotropicLinearMaterial

public AnisotropicLinearMaterial(double E,

AnisotropicLinearMaterial

public AnisotropicLinearMaterial(Matrix6dBase C)

Creates a new AnisotropicLinearMaterial with the specified stiffness tensor. Corotated formulation is used by default.

Parameters:

C - 6x6 Voigt stiffness tensor

AnisotropicLinearMaterial

public AnisotropicLinearMaterial(Matrix6dBase C,
                                 boolean corotated)

Creates a new AnisotropicLinearMaterial with the specified stiffness tensor and corotated flag.

Parameters:

C - 6x6 Voigt stiffness tensor

corotated - if true, use the corotated linear formulation

Method Detail

getAllPropertyInfo

public FieldPropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class LinearMaterialBase

Returns:

static information for all exported properties

createIsotropicStiffness

public static Matrix6d createIsotropicStiffness(double E,
                                                double nu)

getStiffnessTensor

public Matrix6d getStiffnessTensor()

getRasterizedStiffnessTensor

public VectorNd getRasterizedStiffnessTensor()

setRasterizedStiffnessTensor

public void setRasterizedStiffnessTensor(VectorNd C)

setStiffnessTensor

public void setStiffnessTensor(Matrix6d C)

equals

public boolean equals(FemMaterial mat)

Overrides:

equals in class LinearMaterialBase

clone

public AnisotropicLinearMaterial 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 LinearMaterialBase

Returns:

clone of this property

scaleDistance

public void scaleDistance(double s)

Description copied from interface: ScalableUnits

Scales all distance coordinates.

Specified by:

scaleDistance in interface ScalableUnits

Overrides:

scaleDistance in class MaterialBase

Parameters:

s - scaling factor

scaleMass

public void scaleMass(double s)

Description copied from interface: ScalableUnits

Scales all mass units.

Specified by:

scaleMass in interface ScalableUnits

Overrides:

scaleMass in class MaterialBase

Parameters:

s - scaling factor

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
