-
First-order, shear-deformable (Timoshenko) beam elements (B21, B31) should be used in any simulation that includes contact.
-
If the transverse shear deformation is important, use Timoshenko beam
elements (B21, B22, B31, B32).
-
If the structure is either very rigid or very flexible, the hybrid beam
elements (B21H, B32H, etc.) available in
Abaqus/Standard
should be used in geometrically nonlinear simulations.
-
The Euler-Bernoulli (cubic) beams (B23, B33) available in
Abaqus/Standard
are very accurate for simulations that include distributed loading, such as
dynamic vibration analyses.
-
Structures with open, thin-walled cross-sections should be modeled with
the elements that use open-section warping theory (B31OS, B32OS) available in
Abaqus/Standard.
