Beam2 element

 

Figure 1  Beam2 element

 

     Beam2 is a general beam element with the following capabilities:

    Tension

    Compression

    Torsion

    Bending

 

     The element has six degrees of freedom at each node:

    Translations in the nodal x, y, and z directions

    Rotations in the nodal x, y, and z axes

 

     The element is defined by:

    Two nodes

    The cross-sectional area

    Two area moments of inertia

 

     V vector (Orientation vector)

    Element X direction vector is defined a displacement vector from N1 to N2 like figure 1. The Orientation vector V is an perpendicular vector with the element X direction vector.

In the case of FFlex/Beam2 element, the V vector is defined as an Element Y direction vector.

In the case of toolkit Beam element (BeamBelt and R2R Beam), the V vector is defined as an Element Z direction vector.
