Abstract
Optimization is a central concept in the design of composite structures because of the adaptability of composite materials to a given design situation. Design parameters such as layer thicknesses and ply angles can be employed to great effect to achieve an optimized structure with improved weight and stiffness characteristics. This chapter deals with the lay-up optimization of laminated plates subject to buckling loads. A survey of the subject is presented and the optimal configurations of rectangular laminates are discussed. Designs are studied with respect to layer thicknesses and ply angles for symmetrical and antisymmetrical laminates of hybrid and non-hybrid construction. The effect of bending-twisting coupling on optimal designs is discussed and the optimal configurations with and without this effect are compared. Several factors affecting optimal designs are highlighted. These factors include the use of discrete ply angles and layer thicknesses, restrained edges, shear deformation, cut-outs, thermal loading, strength and stiffness constraints, multiple design objectives and shape design.
