Title: Integrated Design of Materials and Products—Robust Topology Design of a Cellular Material
Abstract: This chapter provides an overview of the tradeoffs in the design of prismatic cellular (honeycomb) materials and the multiobjective decision protocols and explains the parametric and topology design methods utilized to explore these tradeoffs. It begins with an example of multifunctional design of cellular structures, for which mathematical construct is applied for multiobjective decision support, the compromise decision support problem (cDSP). The robust topological preliminary design exploration method (RTPDEM) is used for designing complex multiscale materials and products concurrently by topologically and parametrically tailoring them for multifunctional performance that is superior to that of standard designs and less sensitive to variations. This systems-based design approach is formulated by establishing and integrating principles and techniques for robust design, multiobjective decision support, topology design, collaborative design, and design space exploration along with approximate and detailed simulation models. Robust topology design methods are used not only to design material topologies that are relatively insensitive to manufacturing-related imperfections but also to systematically and intentionally create topological designs with built-in flexibility for subsequent modification. This flexibility is the foundation for the multistage, multifunctional robust topology design method. The RTPDEM is applied to a combustor liner example in which multifunctional cellular structures are designed in a collaborative, multistage process.
