Large displacement analysis of laminated beam-type structures

The paper presents a finite element formulation for analysis of 3D framed structures with thin-walled laminated composite cross-sections, using co-rotational approach. considers the effects large displacements on response space frames subjected to conservative and static external loads. Classical lamination theory thin fiber-reinforced laminates has been employed. Stability is performed in load deflection manner formulation. shear strain middle surface assumed be zero, cross-section not distorted its own plane. In order illustrate application proposed formulation, several numerical examples are presented.
