Mechanical frustration and spontaneous polygonal folding in active nematic sheets.

چکیده
We analyze the bending response to light or heat of a solid nematic disk with a director twisted from being radial on the upper surface to be azimuthal on the lower. We find a number of curl lobes determined purely by the geometry of the mechanical frustration that arises during the response.

Programming complex shapes in thin nematic elastomer and glass sheets.
Nematic elastomers and glasses are solids that display spontaneous distortion under external stimuli. Recent advances in the synthesis of sheets with controlled heterogeneities have enabled their actuation into nontrivial shapes with unprecedented energy density. Thus, these have emerged as powerful candidates for soft actuators. To further this potential, we introduce the key metric constraint...
متن کاملOrigami tubes with reconfigurable polygonal cross-sections.
Thin sheets can be assembled into origami tubes to create a variety of deployable, reconfigurable and mechanistically unique three-dimensional structures. We introduce and explore origami tubes with polygonal, translational symmetric cross-sections that can reconfigure into numerous geometries. The tubular structures satisfy the mathematical definitions for flat and rigid foldability, meaning t...
متن کاملApplications of Folding Flat Sheets of Materials into 3-D Intricate Engineering Designs
Folding of flat sheets of material into intricate three-dimensional structures provides a new technology for production of cores and sandwich structures of high strength/weight and/or strength/volume ratios. Geometric patterns are generated by transforming flat sheets of materials (traditional or composite) by imposing a permanent fold at specific edges of tessellated sheets. This might result ...

The Galerkin weighted residuals method is extended solve the laminar, fully developed flow and heat transfer of Al2O3-water nanofluid inside polygonal ducts with round corners for the constant heat flux and uniform wall temperature boundary conditions. Using the method, semi-analytical, closed-form solutions are obtained for the friction coefficient and the Nusselt number in terms of the radius...
متن کاملMagnetic self-assembly of three-dimensional surfaces from planar sheets.
This report describes the spontaneous folding of flat elastomeric sheets, patterned with magnetic dipoles, into free-standing, 3D objects that are the topological equivalents of spherical shells. The path of the self-assembly is determined by a competition between mechanical and magnetic interactions. The potential of this strategy for the fabrication of 3D electronic devices is demonstrated by...
