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.
o In the case of FFlex/Beam2 element, the V vector is defined as an Element Y direction vector.
o In the case of toolkit Beam element (BeamBelt and R2R Beam), the V vector is defined as an Element Z direction vector.
