  bibo_abstract:
  - "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 joints that can be directly printed or assembled in a zero-energy fabrication
    state. During deployment, as the elastic beams of varying heights rotate from
    vertical to horizontal configurations, the entire structure transforms from a
    compact block into a target curved surface. Umbrella Meshes encode both intrinsic
    and extrinsic curvature of the target surface and in principle are free from the
    area expansion ratio bounds of past auxetic material systems.\r\nWe build a reduced
    physics-based simulation framework to accurately and efficiently model the complex
    interaction between the elastically deforming components. To determine the mesh
    topology and optimal shape parameters for approximating a given target surface,
    we propose an inverse design optimization algorithm initialized with conformal
    flattening. Our algorithm minimizes the structure's strain energy in its deployed
    state and optimizes actuation forces so that the final deployed structure is in
    stable equilibrium close to the desired surface with few or no external constraints.
    We validate our approach by fabricating a series of physical models at various
    scales using different manufacturing techniques.@eng"
