“…Here N ij are the in-plane force resultants, M ij are moment resultants, Q i are the transverse shear resultants, h is the total thickness of the laminate and K s is the shear correction coefficient, usually set to 5/6. In general, the stresses in (11) will not be continuous through the thickness of the laminate due to changes in constitutive properties across ply boundaries. Therefore the integral through the thickness has mid-plane to be written as a sum of integrals over the thickness of each ply.…”

“…In structural optimization, the design problem is formulated as a mathematical optimization problem where the purpose is to generate solutions with maximized performance. Performance measures considered in structural optimization of composites include weight [1,2], stiffness [3,4], strength [5,6], residual stress [7,8], buckling [9,10], aeroelasticity [11,12] and cost [13,14]. The focus of the research work has been to develop methods with improved computational efficiency and functionality through the use of more efficient optimization algorithms and handling of new types of manufacturing techniques and design methods [15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Aeroelastic tailoring is a structural design strategy in which the arrangement of mechanical properties leads to more control on the static and dynamic deformations, thereby impacting on the aeroelastic performance of the aircraft [16]. There has been many researches on the application of composite structure for aeroelastic tailoring design [17][18][19][20][21][22]. Not too many research has been encountered for the specific task of aeroelastic tailoring for panel thermal flutter avoidance in the literature.…”

This work investigates thermal aeroelastic tailoring of a laminated composite panel with a lamination parameter-based method. Equivalent membrane and bending coefficients of thermal expansions for symmetric laminated panel are derived and represented with lamination parameters using Classical Laminated Plate Theory. The relationship between thermal flutter behavior and lamination parameters is examined. The optimization process is split into two stages. In the first stage, lamination parameters and laminate thicknesses are as design variables to minimize the structure mass, subject to thermal flutter behavior and feasible region constraints of lamination parameters. In the second-stage, instead of using conventional genetic algorithm, the enhanced JAYA method is extended to search the laminate configuration to target the optimal lamination parameters. The effectiveness of the presented method is demonstrated through a thermal aeroelastic tailoring problem.
