“…14 The critical buckling load is quite sensitive to the anisotropic properties of laminated composite plates, and many studies have treated lay-up and fiber orientation as design variables for buckling optimization of composite plates. 15–18 From the above descriptions, fundamental frequency and buckling load are the critical factors in the design of laminated composite structures, and in the present work, they are also the main concerns to be maximized for optimal lay-up designs.…”

The paper illustrates the application of a two-level approximation method to the lay-up design of laminated structures for maximization of fundamental frequency and buckling load with design constraints. Previously developed for the mass-minimization design, the approximation method was achieved by starting from an initial design of stacking sequence. Benchmark examples have verified its efficacy in dealing with the mass-reduction problems, but it does not have the capability to address the objective-maximization problems, which is mainly due to the limitation of the second-level approximate problem. In this work, this method is improved and extended for the consideration of objective maximization with more design constraints. The second-level approximate problem is reconstructed with mixed direct/reciprocal design variables, suitable for solving maximization problems. By varying different initial designs of stacking sequence and conducting repeated runs in the numerical examples, its efficiency is significantly shown after making comparisons with other methods.

“…Because of the advantages of using laminated composites in structural applications, their performance has been researched extensively. In these fields, various optimization studies have been carried out to maximize the performance of these structures while reducing cost [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Vo-Duy et al [24,25] presented the weight minimization and natural frequency maximization problems of laminated plates using an adaptive elitist differential evolution algorithm treating the ply thicknesses, fiber orientations, and the fiber volume fractions as the variables of optimization.…”

Metaheuristic Optimization of Laminated Composite Plates with Cut-Outs

The stacking sequence optimization of laminated composite plates while maximizing the structural performance or minimizing the weight is a subject investigated extensively in the literature. Meanwhile, research on the optimization of laminates with cut-outs has been relatively limited. Cut-outs being an indispensable feature of structural components, this paper concentrates on the stacking sequence optimization of composite laminates in the presence of circular cut-outs. The buckling load of a laminate is used as a metric to quantify the structural performance. Here the laminates are modeled as carbon fiber-reinforced composites using the finite element analysis software, ABAQUS. For the optimization, the widely used harmony search algorithm is applied. In terms of design variables, ply thickness, and fiber orientation angles of the plies are used as continuously changing variables. In addition to the stacking sequence, another geometric variable to consider is the aspect ratio (ratio of the length of the longer sides to the length of the shorter sides of the plate) of the rectangular laminates. The optimization is carried out for three different aspect ratios. It is shown that, by using dispersed stacking sequences instead of the commonly used 0°/±45°/±90° fiber angle stacks, significantly higher buckling loads can be achieved. Furthermore, changing the cut-out geometry is found to have a significant effect on the structural performance.

“…Kaveh et al [31] investigated the application of the BBO algorithm in stacking sequence optimisation of laminated composite plates for various load cases and aspect ratios to maximise the buckling load factor. HS was utilised by Almeida et al [32] to optimise the buckling load factor of the balanced laminated composite plate under compressive in-plane loads. Akcair et al [33] applied DE and SA to optimise the buckling load factor of the laminated composite plate under different increments in fibre orientations.…”

This paper investigates the performance of several meta-heuristic algorithms, including Particle Swarm Optimisation (PSO), different variants of Differential Evolution (DE), Biogeography-Based Optimisation (BBO), Cultural Algorithm (CA), Optics-Inspired Optimisation (OIO), and League Championship Algorithm (LCA), for optimum layup of laminated composite plates. The study provides detailed Pseudo codes for different algorithms. The buckling capacity maximisation of a 64-layer laminated composite plate under various load scenarios has been considered as the benchmark problem, in which the design variables are the stacking sequences of layers. A Deep Statistical Comparison (DSC) method is employed to rank the performance of different algorithms. The DSC uses a nonparametric two-sample Kolmogorov-Smirnov test to conduct the performance comparisons between the algorithms. The overall performance rankings obtained from the DSC suggest that the LCA, OIO, and PSO algorithms perform remarkably better in comparison to other algorithms. The comparisons provide some interesting conclusions on the performance of different algorithms.
