Zero length element.
The ZeroLength class represents an element defined by two nodes at the same geometric location, hence it has zero length. The nodes are connected by of uniaxial materials to represent the force-deformation relationship for the element. ZeroLength elements are constructed with a tag
in a domain of dimension
1, 2, or 3, connected by nodes {Nd1} and {Nd2}. The vector x
defines the local x-axis for the element and the vector yprime
lies in the local x-y plane for the element. The local z-axis is the cross product between x
and yprime
, and the local y-axis is the cross product between the local z-axis and x
.

Construct element with one unidirectional material (numMaterials1d=1) The force-deformation relationship for the element is given by a pointer theMaterial
to a { UniaxialMaterial} model acting in local direction
. The local direction
is 1, 2, 3, for translation in the local x, y, z axes or 4, 5, 6 for rotation about the local x, y, z axes.

Construct element with multiple unidirectional materials.
Construct a ZeroLength element with tag
. The force-deformation relationship is given by the {n1dMat} pointers theMaterial
to { UniaxialMaterial} models. direction
is an { ID} of length {n1dMat} that gives the local direction for each corresponding entry in the array theMaterial
The local direction
is 1, 2, 3, for translation in the local x, y, z axes or 4, 5, 6 for rotation about the local x, y, z axes.

XC::ZeroLength::~ZeroLength | ( | void | ) |
Destructor: delete must be invoked on any objects created by the object and on the matertial object.
|
virtual |
The element has no mass, so this operation has no effect and returns 0.
Implements XC::Element.
|
virtual |
The element has no loads, so this operation has no effect and returns 0.
Implements XC::Element.
|
virtual |
Commit state of element.
Commit state of element by committing state of materials. Return 0 if successful, !0 otherwise.
Reimplemented from XC::Element.
|
protected |
Return a pointer to the material that corresponds to the name.
matName | name of the material. |
const XC::Vector & XC::ZeroLength::getCurrentDispDiff | ( | void | ) | const |
Compute the current difference in displacements between the nodes.
const XC::Vector & XC::ZeroLength::getCurrentVelDiff | ( | void | ) | const |
Compute the current difference in displacements between the nodes.
|
protectedvirtual |
Returns a vector to store the dbTags of the class members.
Reimplemented from XC::DistributedBase.
const XC::Vector & XC::ZeroLength::getPersistentInitialSectionDeformation | ( | void | ) | const |
Returns the value of the persistent (does not get wiped out by zeroLoad) initial deformation of the section.
|
virtual |
Get response information for responseID
.
Return 0 if successful, -1 otherwise.
Reimplemented from XC::Element.
|
virtual |
Return a python list with the values of the argument property at element nodes.
When the property requested its located at the integration point this function is responsible of the extrapolation of values from Gauss points to nodes.

void XC::ZeroLength::incrementPersistentInitialDeformationWithCurrentDeformation | ( | void | ) |
Increments the persistent (does not get wiped out by zeroLoad) initial deformation of the section.
It's used to store the deformation of the material during the periods in which their elements are deactivated (see alive() method).

virtual |
Revert state of element to last commit.
Revert state of element to last commit by reverting to last committed state of materials. Return 0 if successful, !0 otherwise.
Implements XC::Element.
|
virtual |
Revert state of element to initial.
Revert state of element to initial state by reverting to initial state its materials. Return 0 if successful, !0 otherwise.
Reimplemented from XC::Element.
|
virtual |
Set the elemento domain.
to set a link to the enclosing Domain and to set the node pointers. also determines the number of dof associated with the ZeroLength element, we set matrix and vector pointers, allocate space for t matrix and define it as the basic deformation- displacement transformation matrix.
Reimplemented from XC::Element.
void XC::ZeroLength::setMaterial | ( | const int & | dir, |
const std::string & | matName | ||
) |
Set the material for the direction argument.
dir | direction |
|
virtual |
Set response quantities as "force", "deformation", "material", or "stiff".
Return response ID or -1 if error. Currently, only the one uniaxial material can be set.
Reimplemented from XC::Element.
