dc.description.abstract A number of methods are available to analyze the laminated composite beams using smear property of laminate stiffness ignoring unsymmetrical behavior of laminates . Some include their effect of laminate but did not include the unsymmetrical effect of the cross -section of the beam . On the other hand , using finite element method to analyze the beam is dependent on the structural configurations including the laminate lay -up sequence . An analytical method was developed from lamination theory in order to study the structural response of composite laminated beams . The present method is capable of predicting the axial and bending stiffnesses , the centroid location , and the stresses in each ply of the whole structure . The results were compared with finite element methods . Laminated beams studied in this research include the beams with a rectangular cross -section bonded with a stiffener . The stiffener placed in both aligned and non -aligned position with respect to the centerline of the beam is considered . Thin -walled beams with circular and airfoil sections are also studied . A parametrization method to define the median of the cross -section is developed . Then the stress analysis is conducted . For two laminates aligned bonded together top and bottom , the present method results agree very well with the finite element results for all the cases less the unsymmetrical case . For the non -aligned case , all the results agree . On the other hand , the results also are close to each other for the laminates bonded side by side less the un -balanced case . Finally , for the circular and airfoil cross -sections the results agree with the finite element results . en_US
