SUMMARY:Second-Order Finite Elements for Deformable Surfaces
DESCRIPTION:Technical Papers\n\nQiqin Le (Shanghai Qi Zhi Institute); Yito
 ng Deng (Stanford University); Jiamu Bu (Tsinghua University); Bo Zhu (Geo
 rgia Institute of Technology); and Tao Du (Tsinghua University, Shanghai Q
 i Zhi Institute)\n\nWe present a computational framework for simulating de
 formable surfaces with second-order triangular finite elements. Our method
  develops numerical schemes for discretizing stretching, shearing, and ben
 ding energies of deformable surfaces in a second-order finite-element sett
 ing. In particular, we introduce a novel discretization scheme for approxi
 mating mean curvatures on a curved triangle mesh. Our framework also integ
 rates a virtual-node finite-element scheme that supports two-way coupling 
 between cut-cell rods without expensive remeshing. We compare our approach
  with traditional simulation methods using linear and higher-order finite 
 elements and demonstrate its advantages in several challenging settings, s
 uch as low-resolution meshes, anisotropic triangulation, and stiff materia
 ls. Finally, we showcase several applications of our framework in cloth si
 mulation, mixed Origami and Kirigami, and biologically-inspired soft wing 
 simulation.\n\nRegistration Category: Full Access\n\nSession Chair: Qixing
