“…There are mainly two approaches used to predict failure load of composite laminates: One is the first ply failure criterion (Akbulut and Sonmez 2008;Akbulut and Sonmez 2011), according to which, failure occurs at the instant a damage initiates. This may be true for uniform plates under a uniform stress state.…”

In this study, the structural optimization of notched composite laminates under in plane shear and normal tension loads were carried out. The objective function of the optimization problem was selected to be the maximum stiffness and the minimum strain respectively along with the orientation angles as the optimization variables. In order to determine the ultimate failure load, a previously developed progressive failure approach was adopted. Although numerous studies exist in the literature on this subject, within the scope of the present study, correlations with the experimental results were examined qualitatively by comparing predicted and experimentally determined damage states. Prior to obtaining the optimized results, a further investigation into the response of the structure under pure shear was studied by a parametric approach. A zeroth order optimization tool known as Nelder&Mead was utilized to obtain the optimized configurations. It was shown that the developed optimization scheme is suitable for an exact determination of maximum stiffness and the minimum strain for the given materials and geometry. The results were presented for various load configurations

“…Locating the globally optimal material design with a local search algorithm is almost a hopeless enterprise. For this reason, many researchers preferred global search algorithms like genetic algorithms (Soremekun et al, 2001;Todoroki & Tetsuya, 2004;Kang & Kim, 2005), simulated annealing algorithm (Soares et al, 1995;Jayatheertha et al, 1996;Sciuva et al, 2003;Correia et al, 2003;Erdal & Sonmez, 2005;Moita et al, 2006;Akbulut & Sonmez, 2008), improving hit-and run (Savic et al, 2001). …”

“…Genetic algorithms (GA) have been examined to solve these kinds of problems by different researchers in many studies [6,[9][10][11][12][13]15]. Also, other techniques such as fractal branch and bound method were used by Terada et al [14] and simulated annealing by Akbulut and Sonmez [2]. Recently, a new class of algorithms, the ant colony optimization (ACO), was developed to solve combinatorial optimization problems.…”

Ant colony optimization (ACO) is a class of heuristic algorithms proposed to solve optimization problems. The idea was inspired by the behavior of real ants, related to their ability to find the shortest path between the nest and the food source. ACO has been applied successfully to different kinds of problems. So, this manuscript describes the development and application of an ACO algorithm to find the optimal stacking sequence of laminated composite plates. The developed ACO algorithm was evaluated on four examples for symmetric and balanced lay-up. The results of the first three cases, in which the classical lamination theory was used to obtain the structural response of rectangular plates, were compared to those obtained from the literature using genetic algorithms (GA) and other ACO algorithm. The fourth example investigates the maximization of fundamental frequencies of rectangular plates with central holes, where the structural response was obtained by finite element analysis, showing that this optimization technique may be successfully applied to a broad class of stacking sequence problems for laminated composites.
