Method & Evidence

AimTo optimize the design of a composite sandwich plate for airplane containers to minimize weight and cost while meeting structural performance requirements.
MethodMulti-objective optimization using computational solvers (Excel Solver, Matlab's Genetic Algorithm) combined with material property calculation software (Laminator) based on Classical Lamination Plate Theory and Tsai-Hill failure criteria.
ProcedureExisting aluminum base-plates were conceptually replaced with composite sandwich plates. The sandwich plates were designed with aluminum honeycomb cores and face-sheets made of glass, carbon, or hybrid fibers with varying orientations. A multi-objective optimization process was used to determine the optimal core thickness and number of face-sheet layers, considering nine design constraints related to stiffness, deflection, stress, and buckling. The optimization weighted weight and cost equally.
