Title: Advantageous couplings: the science and math behind multifunctional materials and structures

Abstract: The development of active and adaptive aerospace structures based on the behavior of unique materials has been considered with great fervor especially since the various federally funded efforts of the 1990's. What is new and highly enabling is the increased fidelity of three-dimensional mathematical models and especially the implementation of these models into ever more comprehensive design frameworks. Given the sustained improvement of such design tools, full analysis-driven optimization considering such concepts as coupled fields and uncertainty may soon become common practice in the multifunctional structure design community. This will enable both the increased performance of current concepts and an expansion in creativity regarding the kinds of material and structural configurations considered. This talk will review recent multifunctional material and structures modeling and design efforts with which Dr. Hartl has been involved over the last three years as well as his current research efforts at Texas A&M. Some of the advances in multifunctional aerospace structural modeling and design will be highlighted. Design concepts such as liquid metal-based reconfigurable antennas and morphing components will be described, and design approaches leveraging evolutionary genetic programming will be shared.”
