Mechanics, Materials, and Architectures for Large Shape-Reconfigurable Structures

A myriad of aerospace structures relies on having extremely large sizes for their performance. The common challenge is transporting them and integrating them with other components of the system. Large structures with the ability to undergo extreme shape reconfiguration are highly attractive strategies for such applications. In this talk, I will discuss research efforts on understanding the mechanics, materials, and architectures involved in realizing shape-reconfigurable structures, ranging from deployable booms for solar sailing missions, deployable propeller blades, and high-altitude superpressure balloons. At the core of these shape-changing structures is the intersection of nonlinear thin-shell mechanics, ultrathin composites, time-dependent behavior of polymers, and material architectures.
