Geometry and Mechanics of Ribbon Gridshells
Daniel Castro, Joo-Won Hong, Hillel Aharoni +3
Mechanical metamaterials exhibit anomalous properties induced from non-trivial mesoscopic constituents. Inspired from architectural and industrial structures, we introduce arrangem…
Defect Topology in Colloidal Smectics
Chaya Halperin, Hillel Aharoni
Colloidal smectics -- layered structures formed in dense suspensions of rod-like particles -- often exhibit grain boundaries, across which the layer orientation changes by $90^{\ci…
Unfrustrated Self-Morphing of Bulk Liquid Crystal Elastomers
Shachaf Rotem, Hillel Aharoni
Precise manipulation of shape-morphing responsive materials is crucial for applications in soft robotics and adaptive structures. While notable precision has been achieved in thin…
Inverse Design of Tightly Woven Smart Fabrics
Einav Berin, Hillel Aharoni
We present a geometric framework for the inverse design of smart woven fabrics composed of non-uniformly shrinking threads. A sufficiently tight weaving structure imposes strong lo…
Inverse Design of Parameter-Controlled Disclination Paths
Yehonatan Tsubery, Hillel Aharoni
Topological defects, such as disclination lines in nematic liquid crystals, are fundamental to many physical systems and applications. In this work, we study the behavior of nemati…
Tunable Three-Dimensional Architecture of Nematic Disclination Lines
Alvin Modin, Biswarup Ash, Kelsey Ishimoto +3
Disclinations lines play a key role in many physical processes, from the fracture of materials to the formation of the early universe. Achieving versatile control over disclination…
Shape Morphing of Planar Liquid Crystal Elastomers
Daniel Castro, Hillel Aharoni
We consider planar liquid crystal elastomers: two dimensional objects made of anisotropic responsive materials, that upon activation remain flat however change their planar shape.…
Curved geometries from planar director fields - Solving the two-dimensional inverse problem
Itay Griniasty, Hillel Aharoni, Efi Efrati
Thin nematic elastomers, composite hydrogels and plant tissues are among many systems that display uniform anisotropic deformation upon external actuation. In these materials, the…
Aspects of Defect Topology in Smectic Liquid Crystals
Thomas Machon, Hillel Aharoni, Yichen Hu +1
We study the topology of smectic defects in two and three dimensions. We give a topological classification of smectic point defects and disclination lines in three dimensions. In a…
Making Faces: Universal Inverse Design of Surfaces with Thin Nematic Elastomer Sheets
Hillel Aharoni, Yu Xia, Xinyue Zhang +2
Programmable shape-shifting materials can take different physical forms to achieve multifunctionality in a dynamic and controllable manner. Although morphing a shape from 2D to 3D…
Composite Dislocations in Smectic Liquid Crystals
Hillel Aharoni, Thomas Machon, Randall D. Kamien
Smectic liquid crystals are charcterized by layers that have a preferred uniform spacing and vanishing curvature in their ground state. Dislocations in the smectics play an importa…
Two-dimensional defects in amorphous materials
Michael Moshe, Eran Sharon, Ido Levin +2
We present a new definition of defects which is based on a Riemannian formulation of incompatible elasticity. Defects are viewed as local deviations of the material's reference met…
