Abstract
Three-phase graphene/fibre-reinforced cantilever skew laminates are optimized with the design objective of maximizing the fundamental frequency. Four optimal design problems are formulated involving one, two, three, and four design variables: graphene content, fibre content, layer thicknesses, and the fibre orientations. Optimization is implemented using a Sequential Quadratic Programming optimization algorithm within finite element analysis. It is observed that optimizing the graphene and fibre contents across the thickness leads to increased fundamental frequency. A trend is observed for the frequency of skew laminates to increase but for their design efficiency to decrease compared to rectangular laminates.
