22 Nov Line Elements
Line Elements consist of a starting point (node), an endpoint and the connectivity between the two which can be visualised by a line in 3D space.
Line Elements are suitable to represent beams and trusses, but also for more complex parts such as springs and dampers. They can also be used for tension-only items like chains and ropes. They are widely employed in structural engineering.
On beam elements (line elements representing beams), all 6 Degrees of Freedom (DOF) are defined for the nodes. That means, they are the only FEA elements that support translations and rotations. In this sense, they are the most accurate element type.
Other line elements are variations of beam elements, with one or more DOF constrained.
