An efficient beam element for the analysis of laminated composite beams of thin-walled open and closed cross sections

“…The table shows an excellent agreement between the predictions of the present model and the results of the other models mentioned, especially the results of Lee [8]. Moreover, the present results based on plane stress conditions are found to be closer to the results produced by ABAQUS [20] than the results in [8], [19]. It is further observed that in all cases convergence of the results was achieved using only two elements with the approach proposed herein.…”

“…The values of deflection at the centre of the beam and the bending slope at its supports obtained in the present analysis are presented in Table 1 and Table 2, respectively. The results for the deflections are compared with those of Lee [8] and Lee and Lee [19] in Table 1. Lee [8] considered the effect of transverse shear deformation, whereas the study of Lee and Lee [19] is based on classical lamination theory.…”

Lee [8] considered the effect of transverse shear deformation, whereas the study of Lee and Lee [19] is based on classical lamination theory. In both the studies [8,19], one dimensional finite element analysis has been applied after obtaining the cross-sectional stiffness matrix analytically.…”
