Beam type spring elements are defined as property TYPE13 elements. This type of spring element
functions as if it were a beam element. The six independent modes of deformation
are:
Traction / compression
Torsion
Bending (two modes)
Shear (two modes)
Beam type springs only function if their length is not zero. A physical representation of a beam
type spring can be seen in Figure 1. Figure 1. Representation of Beam Type Spring
