On elastic geodesic grids and their planar to spatial deployment

S Pillwein, K Leimer, M Birsak, P Musialski - arxiv preprint arxiv …, 2020 - arxiv.org
We propose a novel type of planar-to-spatial deployable structures that we call elastic
geodesic grids. Our approach aims at the approximation of freeform surfaces with spatial …

3D weaving with curved ribbons

Y Ren, J Panetta, T Chen, F Isvoranu… - ACM Transactions …, 2021 - infoscience.epfl.ch
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 …

Deployable strip structures

D Liu, D Pellis, YC Chiang, F Rist, J Wallner… - ACM Transactions on …, 2023 - dl.acm.org
We introduce the new concept of C-mesh to capture kinetic structures that can be deployed
from a collapsed state. Quadrilateral C-meshes enjoy rich geometry and surprising relations …

Generalized deployable elastic geodesic grids

S Pillwein, P Musialski - ACM Transactions on Graphics (TOG), 2021 - dl.acm.org
Given a designer created free-form surface in 3d space, our method computes a grid
composed of elastic elements which are completely planar and straight. Only by fixing the …

Merci: Mixed curvature-based elements for computing equilibria of thin elastic ribbons

R Charrondière, S Neukirch… - ACM Transactions on …, 2024 - dl.acm.org
Thin elastic ribbons represent a class of intermediary objects lying in-between thin elastic
plates and thin elastic rods. Although the two latter families of thin structures have received …

[HTML][HTML] An elastic rod in frictional contact with a rigid cylinder

P Grandgeorge, TG Sano, PM Reis - Journal of the Mechanics and Physics …, 2022 - Elsevier
We investigate the load transmission along an elastic rod of finite cross-section in contact
with a rigid cylinder, as system often referred to as the generalized capstan problem. In the …

GeoLatent: A Geometric Approach to Latent Space Design for Deformable Shape Generators

H Yang, B Sun, L Chen, A Pavel, Q Huang - ACM Transactions on …, 2023 - dl.acm.org
We study how to optimize the latent space of neural shape generators that map latent codes
to 3D deformable shapes. The key focus is to look at a deformable shape generator from a …

[HTML][HTML] Indentation and stability of woven domes

S Poincloux, C Vallat, T Chen, TG Sano… - Extreme Mechanics …, 2023 - Elsevier
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 …

Numerical modeling of static equilibria and bifurcations in bigons and bigon rings

T Yu, L Dreier, F Marmo, S Gabriele, S Parascho… - Journal of the …, 2021 - Elsevier
In this study, we explore the mechanics of a bigon and a bigon ring from a combination of
experiments and numerical simulations. A bigon is a simple elastic network consisting of two …

Dev2PQ: Planar quadrilateral strip remeshing of developable surfaces

F Verhoeven, A Vaxman, T Hoffmann… - ACM Transactions on …, 2022 - dl.acm.org
We introduce an algorithm to remesh triangle meshes representing developable surfaces to
planar quad dominant meshes. The output of our algorithm consists of planar quadrilateral …
