Description
Summary:In this study, an optimization procedure is proposed to maximize the safety factor of laminated composite plates subject to in-plane loading. Fiber orientation angles and stacking sequence are chosen as design variables. Genetic Algorithm (GA), which is a reliable global search algorithm, is used to search the optimal design. Static failure criteria are used to determine whether load bearing capacity for a configuration generated during the optimization process. In order to avoid spurious optimal designs, both the Tsai–Wu and the maximum stress criteria are employed to check static failure. Numerical results are obtained and presented for different loading cases.
