“…presented an optimisation process to improve the performance of piezoelectric FG plates by analysing shape control using a multi-objective isogeometric integrated method. Jin and Masatoshi (2015) worked on minimising the flexibility of FG sandwich structures by conduct a reliable design and optimisation analysis using an interface shape method, taking into accounts the volume constraints of the FG part. Zhu et al (2009) presented an optimal study of sandwich panels under impact loading conditions to study the buckling behaviour considering the effect of different design parameters.…”

This study presents the optimum operating parameters and geometrical of the functionally graded sandwich plate with porous materials (FGPMs), widely used in aircraft structures subjected to uniaxial critical buckling load. This process is developed design optimisation parameters by employing Multi-Objective Genetic Algorithm (MOGA) techniques. According to a simple power law, the assumption of varying material characteristics of the porous FG core through the plate thickness is considered. In addition, to evaluate the linear buckling behaviour, a new mathematical model based on the classical plate theory (CPT) is proposed. The impact of different design parameters on the performance of the functionally graded structure is studied. Then, finite element modelling is used to validate the results of the analytical solution. Finally, the optimisation method includes both design of experiments (DOE) and response surface methodology (RSM), which are used to find out the critical buckling load of the FG sandwich plate with porous metal core bonded with two homogenous skins using suitable adhesion. The mandatory constraints are the maximum critical buckling and maximum total deformation. In this work, 100 design points are considered to determine the total deformation load multiplier, maximum deformation, and equivalent stress of sandwich plate with graded materials and even distribution of porosities. The buckling analyses of the FGPM sandwich plate subjected to the compression loading are presented by conducting an experimental program. The results show good convergence between suggested analytical and FEA simulation with an average error percentage of no more than 2 %.

“…Shi and Shimoda [4] showed that the compliance of functionally graded sandwich structures can be reduced significantly by performing an interface shape optimization. Also regarding the design of sandwich structures, Loja et al [5] used PSO to maximize the bending stiffness of unidirectional FG beams considering a mass constraint.…”

“…In order to consider individual properties of practical problems and meet the desired implementation, it is necessary to determine the optimal volume fraction distribution in a FGP under certain constraints. In the foregoing work of optimizing the volume fraction distribution, which is also known as size optimization, the parameters of the distribution function are often taken as variables, and the objective function is defined according to the working conditions; the optimal volume fraction distribution can be obtained using an optimization method (Na and Kim 2009;Roque et al 2016;Daynes et al 2017;Shi and Shimoda 2015;Kou et al 2012). The optimization result depends on the selected distribution function; thus, this approach limits the material variability (Lieu and Lee 2017;Lieu et al 2018).…”
