Abstract

This paper presents an efficient optimization method, based on strain energy distribution and a numerical search, for the minimum weight design of structures made from fiber reinforced composite materials. The optimum design procedure takes into consideration multiple loading conditions and displacement constraints on the structure. Sample problems consisting of both isotropic and composite elements are solved and the results presented.

    However, with increasing complexity, the application of computer based systems in the design process becomes necessary. There is a group of publications [10–14] reporting on optimal design of a laminated plate for a given global stress state using mathematical programming or optimality criteria. The layer thicknesses, the layer orientations, or both are taken as design variables to find weight-minimal solutions considering strength constraints.

    Within this field, optimality conditions based on strain energy or stress fields can be derived but also optimality conditions taking principal stress/strain directories or load path vectors as optimal directions are applied. Strain energy based criteria can be found in [5], where the ply thickness of different straightline fibre formats with different fibre angles (e.g. 0/−45/+45/90) are updated according to a constant strain energy level throughout the structure. Pedersen [29] also derived an approach for optimal fibre orientation according to energy density minimisation for maximum stiffness of the structure.
