Materializing split, mixed, and three-body interactions using rotor-based mechanical hysterons
Oche T. Ali, Faten A. Al Ardat, Jack Feider +4
Interacting hysteretic spins are an appealing model for cyclically-driven athermal disordered matter. Because they provide a basis for storing and processing information from their…
Single-material 4D-printed shape-morphing structures via spatially patterned strain trapping
S M Asif Iqbal, Hang Zhang, Lin Yang +3
A single-step, single-material 4D printing method is developed for programmable structures featuring spatially patterned strain trapping for one-way actuation. This approach enable…
Ordered buckling structures in a twisted crimped tube
Pan Dong, Nathan C. Keim, Joseph D. Paulsen
When a ribbon or tube is twisted far enough it forms buckles and wrinkles. Its new geometry can be strikingly ordered, or hopelessly disordered. Here we study this process in a tub…
Shape of a membrane on a liquid interface with arbitrary curvatures
Zachariah S. Schrecengost, Seif Hejazine, Jordan V. Barrett +2
We study the deformation of a liquid interface with arbitrary principal curvatures by a flat circular sheet. Working first at small slopes, we determine the shape of the sheet anal…
Mechanical hysterons with tunable interactions of general sign
Joseph D. Paulsen
Hysterons are elementary units of hysteresis that underlie many complex behaviors of non-equilibrium matter. Because models of interacting hysterons can describe disordered matter,…
Mechanical memories in solids, from disorder to design
Joseph D. Paulsen, Nathan C. Keim
Solids are rigid, which means that when left undisturbed, their structures are nearly static. It follows that these structures depend on history -- but it is surprising that they h…
A wrinkled cylindrical shell as a tunable locking material
Pan Dong, Mengfei He, Nathan C. Keim +1
A buckled sheet offers a reservoir of material that can be unfurled at a later time. For sufficiently thin yet stiff materials, this geometric process has a striking mechanical fea…
