BENDING,BUCKLLNG AND VIBRATION OF SYMMETRICAL ANGLE-PLYLAMINATES

One of the most important characteristics of symmetric angleply laminates is that there exist two terms, D₁₆ and D₂₆ of bending twisting coupling, that makes it almost impossible to obtain, by using traditional series expansion method, the exact solution.In this present paper, the two-step expansion (TSE) technique, proposed recently by the first author, is employed to give a general solution for bending, buckling and vibration of symmetric angle-ply rectangular laminates.
