Computational Design of Flexible Planar Microstructures

We design flexible microstructures that emulate desired elastic materials over finite regions of macrosopic strain space.

Bistable Auxetic Surface Structures

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

A Low-Parametric Rhombic Microstructure Family for Irregular Lattices

New fabrication technologies have significantly decreased the cost of fabrication of shapes with highly complex geometric structure. One important application of complex fine-scale geometric structures is to create variable effective elastic material …

Rapid Deployment of Curved Surfaces via Programmable Auxetics

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

Worst-Case Stress Relief for Microstructures

We introduce an efficient worst-case analysis for periodic microstructures and use it to design robust microstructures.

Thesis: Fine-scale Structure Design for 3D Printing

My thesis develops tools for designing and analyzing objects that leverage the flexibility and resolution of 3D printing.

Fine-Scale Structure Design

This poster summaries our Elastic Textures paper and ongoing work on worst-case stress minimization.

Elastic Textures for Additive Fabrication

We design 3D-printable elastic metamaterials and use them to create deformable objects with single-material printers.
