... of any spatial beam with bisymmetric cross-section that accurately captures the nonlinear load–displacement relations of the spatial beam for intermediate range of end-displacements. The model, referred to as the spatial beam constraint model (SBCM) not only accommodates small initial tilts with respect...

.... However, the primary nonlinear effects (load-stiffening, kinematic, and elastokinematic) arising due to the axial force f x 1 and beam arc-length conservation are largely independent of the twist and therefore would remain the same. This results in a new spatial-beam constraint model...

...-stiffening, kinematic, and elastokinematic effects. The proposed beam constraint model incorporates a wide range of loading conditions, boundary conditions, initial curvature, and beam shape. The accuracy and effectiveness of the proposed beam constraint model is verified by nonlinear finite elements...

...Shorya Awtar; Shiladitya Sen The beam constraint model (BCM), presented previously, captures pertinent nonlinearities to predict the constraint characteristics of a generalized beam flexure in terms of its stiffness and error motions. In this paper, a nonlinear strain energy formulation...
