Proposed generic optimization model for metal sandvich plates during extrusion of thin walled solid sections

The increasing use of metal sandwich structures is absed on their desireable properties such as stiffness and high strenght per unite mass with acceptable prices and good overall properties. The objective of this paper is to propose a generic approach for the problem of optimizing the metal-metal sandviches with corrugated core by treating them as structural elements. The generic model proposed here is a possible way to arrive at optimalstructural designs for given conditions. The objective functions and constrains are derived and presented in conceptual-generalized form. This approach could provide designs that demonstrate significant savings in production of the plates, while preserving the neccessary properties and load capacity. It is planned that the proposed model will be solved using nonlinear programming methods including the evolutionary algorithms for several particular case. The 'product development' cycle also includes the planning of development and manufacturing of several prototypes and experimental testing of some designs.
