Popis:	A novel model describing the shear lag of laminated composite thin-walled beams with openings has been developed. Warping of open-closed cross- sections is defined by displacements parameters at selected nodes. Vlasov’s assumption of neglecting shear strains in the middle surface is not necessary and stresses can be calculated directly from the strains. The general approach to the solution of the problem is based on the finite element method and linear stiffness matrix has been derived using the principle of virtual displacements. Computing program has been developed and numerical results for thin-walled laminated beams with openings have been presented.
