Abstract
Deployable structures have found widespread applications in engineering because of their ability to change shape and size significantly. Combining rods and sheets brings together their advantages for designing deployable structures. We showcase the vast design space that can be achieved with rods and sheets and discuss the plan for exploring the design space using computational methods.
In this proposal, we also discuss three papers that cover three essential aspects of the modeling of rod-sheet deployable structures: a reduced model for elastic rods, a discretization scheme for simulating sheet curvature, and a robust contact handling technique between elements.
