Buckling of thin-walled beams by a refined theory

Journal of Zhejiang University SCIENCE A, 2012
The buckling of thin-walled structures is presented using the 1D finite element based refined beam theory formulation that permits us to obtain N-order expansions for the three displacement fields over the section domain. These higher-order models are obtained in the framework of the Carrera unified formulation (CUF).

On the Modelling of Thin Walled Beams

2015
Thin Walled Beams (TWBs) can be modelled as three dimensional bodies, shell, folded plates or, as their shape seems to suggest, as one dimensional continua. In the last case it must be pointed out that, also in the framework of the linear elasticity, the Saint-Venant solutions can not apply, in most of the cases, to those structures.

Single- and Multicelled Composite Thin-Walled Beams

AIAA Journal, 2002
structed from a general variational-asymptotic framework. The results of the theory are contained in closed-form expressions for the stiffness matrices of single- and double-celled composite thin-walled beams. The accuracy of the approach is demonstrated by several examples.

Non-linear analysis of thin-walled, open beams

Computers & Structures, 1987
A finite-element formulation for the elastic nonlinear static analysis of thin-walled, open beams under combined bending and torsion is presented. The solution strategy is to use the Newton-Raphson method to proceed to the limit point region and then to employ the modified Riks-Wempner constant arc length to traverse the limit point region.

Thin-walled beams

Chapter 4 addresses the behavior of rectilinear, thin-walled beams in torsional response. First, it shows how open and closed profiles are affected by generally developed warping in a thin-walled section while considering the profile contour to be undeformable.

The deformation of beams structured by thin walls

Composite Structures, 2004
Abstract Nowadays our society demands the reuse of industrial products. Then we should not only re-investigate the materials of products but also originate a new design method of industrial products. We have investigated the cellular structure by using abandoned paper, because the cell's shape can be proposed arbitrarily by folding a paper.

End effects in thin-walled beams

37th Structure, Structural Dynamics and Materials Conference, 1996
The nature of end effects for prismatic beams with thin-walled, open cross sections is analyzed by the variational-asymptotic method. This way, the decay rates for disturbances at the ends of prismatic beams are correctly evaluated. Thus, the foundations of Vlasov's theory, as well as restrictions on its applicability, are obtained from the variational-

Theory of Anisotropic Thin-Walled Beams

Journal of Applied Mechanics, 2000
Asymptotically correct, linear theory is presented for thin-walled prismatic beams made of generally anisotropic materials. Consistent use of small parameters that are intrinsic to the problem permits a natural description of all thin-walled beams within a common framework, regardless of whether cross-sectional geometry is open, closed, or strip-like ...
