Method Detail

getAllPropertyInfo

public PropertyList 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 MaterialBase

Returns:

static information for all exported properties

getForce

public double getForce()

setForce

public void setForce(double force)

computeF

public double computeF(double l,
                       double ldot,
                       double l0,
                       double excitation)

Specified by:

computeF in class AxialMaterial

computeDFdl

public double computeDFdl(double l,
                          double ldot,
                          double l0,
                          double excitation)

Specified by:

computeDFdl in class AxialMaterial

computeDFdldot

public double computeDFdldot(double l,
                             double ldot,
                             double l0,
                             double excitation)

Specified by:

computeDFdldot in class AxialMaterial

isDFdldotZero

public boolean isDFdldotZero()

Description copied from class: AxialMaterial

Returns true if computeDFdldot() always returns zero. For a linear spring, this simply means the damping is zero. When dFdldot is always 0, then stiffness matrix will be symmetric.

Specified by:

isDFdldotZero in class AxialMaterial

equals

public boolean equals(AxialMaterial mat)

Overrides:

equals in class AxialMaterial

clone

public ConstantAxialMaterial 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 AxialMaterial

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
