Shape-morphing structures

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.

We present an algorithmic approach to discover, study, and design multistable elastic knots, physical realizations of closed curves embedded in 3-space.

We present a computational inverse design framework for a new class of volumetric deployable structures that have compact rest states and deploy into bending-active 3D target surfaces. *Umbrella meshes* consist of elastic beams, rigid plates, and …

Simulation and inverse design for 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.

We optimize the shapes of *curved* planar laser-cut ribbons that weave into faithful approximations of smooth free-form geometries.

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

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