Optimization of Laminates for Maximum Buckling Load

Objective of this work is to optimize the structural configuration of laminates in terms of design for the maximization of buckling resistance of laminates under the effect of constraints. The predominant design parameter is the orientation of the fibers in the layers of the laminate. High-order deformation theory is used in the mathematical formulation in the buckling analysis of stratified composite plates. For this purpose, we will use the optimization technique genetic algorithm taking into account the various factors: number of fibers, geometric ratio, load ratio and boundary conditions.
