A general isogeometric polar approach for the optimisation of variable stiffness composites: Application to eigenvalue buckling problems

G. A. Fiordilino et al.

Summary: This study introduces a general approach for the multi-scale design of variable stiffness composites, by solving the first-level problem of a two-level optimisation strategy to determine the optimal distribution of stiffness properties. Analytical expressions for the gradient of the buckling factor using polar formalism and B-Spline surfaces were derived, and the impact of discrete variables on the optimised solution was investigated. The approach outperformed existing literature results in terms of maximizing the buckling load of VSC laminates.

Strength and mass optimisation of variable-stiffness composites in the polar parameters space

Michele Iacopo Izzi et al.

Summary: This work presents a general theoretical and numerical framework for the strength and mass optimisation of variable-stiffness composite laminates (VSCLs). The optimisation is performed by solving the failure load maximisation and mass minimisation problems under different scenarios of VSCL macroscopic behavior. Numerical results demonstrate considerable improvements compared to traditional structures and literature-based solutions.
