Deployable structures

Computational Homogenization for Inverse Design of Surface-based Inflatables

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.

C-shells: Deployable Gridshells with Curved Beams

We introduce a computational pipeline for simulating and designing C-shells, deployable structures composed of beams with *curved* planar rest shapes.

Computational Inverse Design of Surface-based Inflatables

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.

Bistable Auxetic Surface Structures

We optimize patterns that, when cut into a flat rubber sheet, produce *bistable* auxetic metamaterials encoding curved target geometries.

X-Shell Pavilion: A Deployable Elastic Rod Structure

Our first-prize-winning pavilion for the IASS 2019 Pavilion Competition.

X-Shells: A New Class of Deployable Beam Structures

X-Shells are a new class of deployable structures formed by an ensemble of elastic beams coupled by rotational joints.

Rapid Deployment of Curved Surfaces via Programmable Auxetics

We program curved surfaces into flat sheets by optimizing a strain-limited auxetic metamaterial.
