Skin Panel Optimization of the Common Research Model Wing Using Sandwich Composites

“…A novel lamination parameters scheme is proposed in [34] that is applicable to sandwich composites, or multi-material laminates in general and is summarized here. This approach is based on the definition of material blocks with an offset in between its two laminate halves.…”

“…Practical experience shows that their benefits come alongside a number of unique engineering challenges, which must be carefully considered in realistic designs [13]. The potential advantages and challenges have motivated a wide range of research covering topics such as characterization of failure modes [14][15][16], development of modelling strategies [17,18] and on optimization of sandwich composites [10][11][12][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. Some of the relevant literature pertaining to the latter have been discussed further.…”

“…An analytical solution for facesheet wrinkling and structural buckling are introduced, while the optimal weight of the sandwich composite is obtained using a multi-step sequential approach. A recently presented work [34] by the authors proposes a novel lamination parameter scheme applicable to sandwich composites. In the paper, a sandwich beam is optimized for maximum load-carrying ability subjected to various structural and feasibility constraints.…”

A general optimization strategy for composite sandwich structures

“…Thus, as such, the representation used here may not be used for hybrid laminates (two or more different kinds of layers). An extension of the lamination parameters scheme for hybrid laminates is presented in [36].…”

“…The method was used to minimize the mass of a sandwich plate under in-plane loading with strength and buckling constraints, using closed-form solutions. Silva and Meddaikar [36] extended the lamination parameters scheme used in the first optimization step for sandwich panel and hybrid laminate design. Catapano and Montemurro [8,9] proposed another two-step strategy, further developed in [31].…”
