Timoshenko's and Vlasov's beam theories are combined to produce a Co finite element formulation for arbitrary cross section thin-walled beams. Section properties are generated using a curvilinear co-ordinate system to describe the cross section dimensions. The element includes both shear and warping

## Abstract Numerical models for finite element analyses of assemblages of thin‐walled open‐section profiles are presented. The assumed kinematical model is based on Timoshenko–Reissner theory so as to take shear strain effects of non‐uniform bending and torsion into account. Hence, strain elastic‐

A six-node, plane-stress mixed finite element model has been developed by using Hamilton's energy principle for the natural vibrations of laminated composite beams. Continuity of the transverse stress and displacement fields has been enforced through the thickness of the laminated beam in the formul
