The implementation of each element is provided in each derived-class. The name of each element derived-class has the following structure:

Formulation-Dimension-Name-nNodes.hpp

.

Name	Description
Formulation	Stands for either Linearized (small deformations), or Kinematic (large deformations).
Dimension	One-dimensional (1D), two-dimensional (2D), or three-dimensional (3D).
Name	The abbreviated name of the element.
nNodes	The number of nodes that conforms the element.

The Element class defines an element in a finite element Mesh. The Element class is designed to:

Have an internal structure suitable for linear and nonlinear behavior.
Provide with functionalities that allow to construct mass, damping, and stiffness matrices as well as force vector.

The main member function in Element are:

Element::CommitState()
This function sets the trial stated as converged ones in Material or Section.
Element::UpdateState()
This function updates the Material and Section states.

Each derived class are provided with the member function:

Element::ComputeMassMatrix()
This function compute the lumped/consistent mass matrix of the element.
Element::ComputeStiffnessMatrix()
This function compute the stiffness matrix of the element using gauss-integration or close form solutions.
Element::ComputeInternalForces()
This function compute the internal vector forces acting on the element.

The following are element derived classes available in SVL:
