SUMMARY:Second-Order Finite Elements for Deformable Surfaces
DESCRIPTION:Qiqin Le (Shanghai Qi Zhi Institute); Yitong Deng (Stanford Un
 iversity); Jiamu Bu (Tsinghua University); Bo Zhu (Georgia Institute of Te
 chnology); and Tao Du (Tsinghua University, Shanghai Qi Zhi Institute)\n\n
 We present a computational framework for simulating deformable surfaces wi
 th second-order triangular finite elements. Our method develops numerical 
 schemes for discretizing stretching, shearing, and bending energies of def
 ormable surfaces in a second-order finite-element setting. In particular, 
 we introduce a novel discretization scheme for approximating mean curvatur
 es on a curved triangle mesh. Our framework also integrates a virtual-node
  finite-element scheme that supports two-way coupling between cut-cell rod
 s without expensive remeshing. We compare our approach with traditional si
 mulation methods using linear and higher-order finite elements and demonst
 rate its advantages in several challenging settings, such as low-resolutio
 n meshes, anisotropic triangulation, and stiff materials. Finally, we show
 case several applications of our framework in cloth simulation, mixed Orig
 ami and Kirigami, and biologically-inspired soft wing simulation.\n\nRegis
