Indentation and stability of woven domes
Pedro Miguel Nunes Pereira de Almeida Reis, Célestin Vallat, Tian Chen, Tomohiko Sano, Samuel Jean Bernard Poincloux
Discrete domes are doubly curved structures comprising a network of beam-like elements. We study the mechanics of discrete domes made of ribbons woven in a pentagonal triaxial pattern. Experiments and finite element simulations are performed to characteriz ...
ELSEVIER2023BamX: Rethinking Deployability in Architecture through Weaving
Mark Pauly, Stefana Parascho, Seiichi Eduardo Suzuki Erazo, Tian Chen, Yingying Ren
Deployable gridshells are a class of planar-to-spatial structures that achievea 3D curved geometry by inducing bending on a flat grid of elastic beams. However, theslender nature of these beams often conflicts with the structure’s load-bearing capacity.To ...
De Gruyter2023Computational Design of Flexible Planar Microstructures
Mark Pauly, Francis Julian Panetta, Tian Chen, Christopher Brandt, Jean Jouve
Mechanical metamaterials enable customizing the elastic properties of physical objects by altering their fine-scale structure. A broad gamut of effective material properties can be produced even from a single fabrication material by optimizing the geometry ...
2023Leveraging the Snap Buckling of Bistable Magnetic Shells to Design a Refreshable Braille Dot
Pedro Miguel Nunes Pereira de Almeida Reis, Tian Chen, Arefeh Abbasi, Bastien Freddy Gustave Aymon
A design concept is proposed for the building block, a dot, of programmable braille readers utilizing bistable shell buckling, magnetic actuation, and pneumatic loading. The design process is guided by Finite Element simulations, which are initially valida ...
Hoboken2023Umbrella Meshes: Elastic Mechanisms for Freeform Shape Deployment
Mark Pauly, Florin Isvoranu, Uday Kusupati, Tian Chen, Yingying Ren, Davide Pellis
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 hinge joint ...
2022The Canopy Pavilion: A lightweight shading structure using a deployable auxetic linkage membrane
Mark Pauly, Dieter Dietz, Florin Isvoranu, Arthur François Blanc, Tian Chen, Etienne Bouleau
We present the Canopy Pavilion, a lightweight shading structure for a social gathering space. The shading surface is realized as a tensioned auxetic linkage membrane, composed of two double-curved anticlastic layers separated by a compression pole. The mem ...
2022From kirigami to hydrogels: a tutorial on designing conformally transformable surfaces
Tian Chen, Yingying Ren, Yue Wang
Elastic surfaces that morph between multiple geometrical configurations are of significant engineering value, with applications ranging from the deployment of space-based PV arrays, the erection of temporary shelters, and the realization of flexible displa ...
20223D Weaving with Curved Ribbons
Mark Pauly, Florin Isvoranu, Tian Chen, Yingying Ren, Samuel Jean Bernard Poincloux, Christopher Brandt
Basket weaving is a traditional craft for creating curved surfaces as an interwoven array of thin, flexible, and initially straight ribbons. The three-dimensional shape of a woven structure emerges through a complex interplay of the elastic bending behavio ...
ASSOC COMPUTING MACHINERY2021Bistable Auxetic Surface Structures
Mark Pauly, Tian Chen, Max Schnaubelt
We present Bistable Auxetic Surface Structures, a novel deployable material system based on optimized bistable auxetic cells. Such a structure can be flat-fabricated from elastic sheet material, then deployed towards a desired double-curved target shape by ...
ASSOC COMPUTING MACHINERY2021Bending Response of a Book with Internal Friction
Pedro Miguel Nunes Pereira de Almeida Reis, Tian Chen, Samuel Jean Bernard Poincloux
We study the bending of a booklike system, comprising a stack of elastic plates coupled through friction. The behavior of this layered system is rich and nontrivial, with a nonadditive enhancement of the apparent stiffness and a significant hysteretic resp ...
