Snap buckling of bistable beams under combined mechanical and magnetic loading
Arefeh Abbasi, Tomohiko G. Sano, Dong Yan +1
We investigate the mechanics of bistable, hard-magnetic, elastic beams, combining experiments, finite element modeling (FEM), and a reduced-order theory. The beam is made of a hard…
A Kirchhoff-like theory for hard magnetic rods under geometrically nonlinear deformation in three dimensions
Tomohiko G. Sano, Matteo Pezzulla, Pedro M. Reis
Magneto-rheological elastomers (MREs) are functional materials that can be actuated by applying an external magnetic field. MREs comprise a composite of hard magnetic particles dis…
The shapes of physical trefoil knots
Paul Johanns, Paul Grandgeorge, Changyeob Baek +3
We perform a compare-and-contrast investigation between the equilibrium shapes of physical and ideal trefoil knots, both in closed and open configurations. Ideal knots are purely g…
Technical Brief: Finite Element Modeling of Tight Elastic Knots
Changyeob Baek, Paul Johanns, Tomohiko G. Sano +2
We present a methodology to simulate the mechanics of knots in elastic rods using geometrically nonlinear, full three-dimensional (3D) finite element analysis. We focus on the mech…
Mechanics of two filaments in tight contact: The orthogonal clasp
Paul Grandgeorge, Changyeob Baek, Harmeet Singh +5
Networks of flexible filaments often involve regions of tight contact. Predictively understanding the equilibrium configurations of these systems is challenging due to intricate co…
Twist-induced snapping in a bent elastic ribbon
Tomohiko G. Sano, Hirofumi Wada
Snapping of a slender structure is utilized in a wide range of natural and man-made systems, mostly to achieve rapid movement without relying on muscle-like elements. Although seve…
Anomalous snapping behavior in asymmetrically constrained elastic strips
Tomohiko G. Sano, Hirofumi Wada
When a flat elastic strip is compressed along its axis, it is bent in one of two possible directions via spontaneous symmetry breaking and forms a cylindrical arc, a phenomenon wel…
Slip Morphology of Elastic Strips on Frictional Rigid Substrates
Tomohiko G. Sano, Tetsuo Yamaguchi, Hirofumi Wada
The morphology of an elastic strip subject to vertical compressive stress on a frictional rigid substrate is investigated by a combination of theory and experiment. We find a rich…
Numerical analysis of impact processes of granular jets
Tomohiko G. Sano, Hisao Hayakawa
The rheology of a three-dimensional granular jet during an impact is investigated numerically. The cone-like scattering pattern and the sheet-like pattern observed in an experiment…
Simulation of granular jet: Is granular flow really a "perfect fluid?"
Tomohiko G. Sano, Hisao Hayakawa
We perform three-dimensional simulations of a granular jet impact for both frictional and frictionless grains. Small shear stress observed in the experiment[X. Cheng et al., Phys.…
