Geometry, mechanics and actuation of intrinsically curved folds
Fan Feng, Klaudia Dradrach, Michał Zmyślony +2
We combine theory and experiments to explore the kinematics and actuation of intrinsically curved folds (ICFs) in otherwise developable shells. Unlike origami folds, ICFs are not b…
Surface instability in a nematic elastomer
Morgan Barnes, Fan Feng, John S. Biggins
Liquid crystal elastomers (LCEs) are soft phase-changing solids that exhibit large reversible contractions upon heating, Goldstone-like soft modes and resultant microstructural ins…
Cellular Topology Optimization on Differentiable Voronoi Diagrams
Fan Feng, Shiying Xiong, Ziyue Liu +6
Cellular structures manifest their outstanding mechanical properties in many biological systems. One key challenge for designing and optimizing these geometrically complicated stru…
Theorem on the Compatibility of Spherical Kirigami Tessellations
Xiangxin Dang, Fan Feng, Huiling Duan +1
We present a theorem on the compatibility upon deployment of kirigami tessellations restricted on a spherical surface with patterned slits forming freeform quadrilateral meshes. We…
Theorem for the design of deployable kirigami tessellations with different topologies
Xiangxin Dang, Fan Feng, Huiling Duan +1
The concept of kirigami has been extensively utilized to design deployable structures and reconfigurable metamaterials. Despite heuristic utilization of classical kirigami patterns…
Origami spring-inspired shape morphing for flexible robotics
Qianying Chen, Fan Feng, Pengyu Lv +1
Flexible robotics are capable of achieving various functionalities by shape morphing, benefiting from their compliant bodies and reconfigurable structures. Here we construct and st…
Interfacial metric mechanics: stitching patterns of shape change in active sheets
Fan Feng, Daniel Duffy, Mark Warner +1
A flat sheet programmed with a planar pattern of spontaneous shape change will morph into a curved surface. Such metric mechanics is seen in growing biological sheets, and may be e…
Shape programming lines of concentrated Gaussian curvature
D. Duffy, L. Cmok, J. S. Biggins +7
Liquid crystal elastomers (LCEs) can undergo large reversible contractions along their nematic director upon heating or illumination. A spatially patterned director within a flat L…
Origami and materials science
Huan Liu, Paul Plucinsky, Fan Feng +1
Origami, the ancient art of folding thin sheets, has attracted increasing attention for its practical value in diverse fields: architectural design, therapeutics, deployable space…
Inverse design of deployable origami structures that approximate a general surface
Xiangxin Dang, Fan Feng, Paul Plucinsky +3
Shape-morphing finds widespread utility, from the deployment of small stents and large solar sails to actuation and propulsion in soft robotics. Origami structures provide a templa…
Evolving, complex topography from combining centers of Gaussian curvature
Fan Feng, John S. Biggins, Mark Warner
Liquid crystal elastomers and glasses can have significant shape change determined by their director patterns. Cones deformed from circular director patterns have non-trivial Gauss…
The designs and deformations of rigidly and flat-foldable quadrilateral mesh origami
Fan Feng, Xiangxin Dang, Richard D. James +1
Rigidly and flat-foldable quadrilateral mesh origami is the class of quadrilateral mesh crease patterns with one fundamental property: the patterns can be folded from flat to fully…
Helical Miura Origami
Fan Feng, Paul Plucinsky, Richard D. James
We characterize the phase-space of all Helical Miura Origami. These structures are obtained by taking a partially folded Miura parallelogram as the unit cell, applying a generic he…
Phase transformations and compatibility in helical structures
Fan Feng, Paul Plucinsky, Richard D. James
We systematically study phase transformations from one helical structure to another. Motivated in part by recent work that relates the presence of compatible interfaces with proper…
