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 LinearAxialMaterial

Returns:

static information for all exported properties

getMaxForce

public double getMaxForce()

setMaxForce

public void setMaxForce(double max)

getMaxForceMode

public PropertyMode getMaxForceMode()

setMaxForceMode

public void setMaxForceMode(PropertyMode mode)

computeF

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

Overrides:

computeF in class LinearAxialMaterial

computeDFdl

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

Overrides:

computeDFdl in class LinearAxialMaterial

computeDFdldot

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

Overrides:

computeDFdldot in class LinearAxialMaterial

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.

Overrides:

isDFdldotZero in class LinearAxialMaterial

equals

public boolean equals(AxialMaterial mat)

Overrides:

equals in class LinearAxialMaterial

clone

public SimpleAxialMuscle 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 LinearAxialMaterial

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 LinearAxialMaterial

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 LinearAxialMaterial

Parameters:

s - scaling factor
