Description A six-node. plane-stress mixed finite element model has been developed by using Hamilton's energy principle for the natural vibrations of laminated composite beams. Continuity, of the transverse stress and displacement fields has been enforced through the thickness of the laminated beam in the formation for proper modelling. The transverse stress components have been invoked as the nodal degrees of freedom by applying elasticity relations. Natural Frequencies of laminated composite beams obtained through the present formulation have been shogun to be in good agreement with the data available in the literature. Various mode shapes have also been presented as benchmark solutions. (C) 2002 . .
