SUMMARY:C-shells: Deployable Gridshells with Curved Beams
DESCRIPTION:Technical Papers\n\nQuentin Becker, Seiichi Suzuki, and Yingyi
 ng Ren (EPFL); Davide Pellis (ISTI - CNR); Julian Panetta (University of C
 alifornia Davis); and Mark Pauly (EPFL)\n\nWe introduce a computational pi
 peline for simulating and designing C-shells, a new class of planar-to-spa
 tial deployable linkage structures. A C-shell is composed of curved flexib
 le beams connected at rotational joints that can be assembled in a stress-
 free planar configuration. When actuated, the elastic beams deform and the
  assembly deploys towards the target 3D shape.\n\nWe propose two alternati
 ve computational design approaches for C-shells: (i) Forward exploration s
 imulates the deployed shape from a planar beam layout provided by the user
 . Once a satisfactory overall shape is found, a subsequent design optimiza
 tion adapts the beam geometry to reduce the elastic energy of the linkage 
 while preserving the target shape.\n(ii) Inverse design is facilitated by 
 a new geometric flattening method that takes a  design surface as input an
 d computes an initial layout of piecewise straight linkage beams. Our desi
 gn optimization algorithm then calculates the smooth curved beams to best 
 reproduce the target shape at minimal elastic energy.\n\nWe find that C-sh
 ells offer a rich space for design and show several studies that highlight
  new shape topologies that cannot be achieved with existing deployable lin
 kage structures.\n\nRegistration Category: Full Access\n\nSession Chair: W
