We develop an effcient homogenization technique for analyzing the contractions and stiffnesses of periodic inflatable patterns and use it for inverse design of general surface-based inflatables.
We introduce a computational pipeline for simulating and designing C-shells, deployable structures composed of beams with *curved* planar rest shapes.
Fusing two sheets along parallel curves creates pockets that inflate into tubes and deform into a curved 3D shape; we optimize the fusing curve network to reproduce an input geometry.
We optimize patterns that, when cut into a flat rubber sheet, produce *bistable* auxetic metamaterials encoding curved target geometries.
Our first-prize-winning pavilion for the IASS 2019 Pavilion Competition.
X-Shells are a new class of deployable structures formed by an ensemble of elastic beams coupled by rotational joints.
We program curved surfaces into flat sheets by optimizing a strain-limited auxetic metamaterial.
