Abstract

This paper deals with the parametric optimisation of a simply supported sandwich panel made of honeycomb composite structure using sequential quadratic programming SQP. The panel consists of aluminum honeycomb sandwiched between two orthotropic fiberglass faces. The parameters studied are fibreglass thickness, tf, honeycomb height, h, and honeycomb wall thickness, tc. The objective was to minimise weight to bending stiffness ratio by using the nonlinear MATLAB function fmincon, considering the maximum central displacement and intercellular buckling as the constraints. Following this, a static structural analysis was conducted on the optimised structure using the open source finite element solver CalculiX and Salome Platform software for preprocessing. The utmost displacement of the honeycomb panel was desirably less than the serviceability limit. Preliminary results show that composite honeycomb structures can be optimised yielding low weight to bending stiffness ratio using SQP method and CalculiX for design evaluation.
