/BEAM - Beam Elements

Description

Describes the beam elements. Two properties (/PROP/TYPE3 and /PROP/TYPE18) are available for this beam element. The properties describing a beam element are all defined in a local beam coordinate system.

hmtoggle_plus1Comments
1.The identifier (ID) must be unique in each element family, but it is advised for each element type to have a unique element identifier in the global model.
2.More than one beam block may be used to define a part.
3.Any number of beams may be defined in one block.
4.Local coordinate system of beam:

Nodes 1 and 2 define local X-axis.

Nodes 1, 2 and 3 define local axis (X,Y) plane at time t =0.

The third node is only used to define initial local frame position.

Z axis is orthogonal to (X,Y) plane.
