Abstract

This paper intends to lay out a possible approach to optimizing the metal-metal sandwich plates with corrugated cores based on a number of assumptions and for certain selected cases. The objective functions and constraints are derived based on standard requirements of minimum weight and satisfaction of static, structural, and design constraints.
The intention of the approach and optimization model presented here is to be able to define the optimum geometry (design) of the sandwich plate for given conditions. With an additional module also developed by the authors, one can design the tool (profiled rolls) that will generate the ‘optimal’ geometry of the corrugated core. In this sense, the approach is actually one of product development based on optimization. More particularly, starting from case-specific given load and optimality conditions one can numerically derive the optimized shape and dimensions of the sandwich and sequentially numerically derive the corresponding production tool geometry, thereby completing the optimized product development.
