DISCRETE MODEL FOR THE ANALYSIS OF THIN AND THICK COMPOSITE BEAM STRUCTURES

In this paper a finite element model for the static analysis of multi-laminated composite or sandwich beams is presented. The model is based on the nonlinear transverse shear deformation theory with nonlinear transverse displacement. This theory enables the nonlinear variation of displacements through the composite beam thickness, thus eliminating the use of shear correction factors. This nonlinear shear deformation model is based on a four node cubic element, enabling the realistic prediction of interlaminar stresses. The transverse shear stress and normal stress perpendicular to geometric axis of the beam, are evaluated directly through the integration of the equilibrium equations. The efficiency and accuracy of the model are discussed with reference to the applications.
