Within this paper, we develop an extension to traditional graphical material selection techniques to create maps of the optimal materials for designs with limiting mechanisms which vary. We apply these techniques to pressurized structures that perform multiple functions and have functional systems embedded within them. Specifically, we consider a conceptual analysis for a pressurized radome and a microvascular composite with active thermal management. The latter is the basis for a liquid metal based Structurally Embedded Vascular Antenna (SEVA) with the potential to tune over a broad range of RF frequencies.
