Abstract : In this report, finite element formulations were developed for symmetrically laminated composite beams and plates for static and free vibration analyses. First, a formulation, an efficient solution procedure, a microcomputer program, and a graphics routine for a 12 d.o.f. anisotropic symmetrically laminated beam finite element including the effect of shear deformation is introduced. The emphasis of the formulation and solution procedure is for simplicity, efficiency, and easy implementation on microcomputers. The formulation, solution procedure, and the program have been evaluated by performing a systematic choice of examples; wherever possible, the present solutions are compared with alternative existing solutions. Second, an 18 d.o.f. triangular plate element in bending with anisotropic symmetrically laminated composite materials is formulated. Keywords: Composite materials, Microcomputer.
