Emergent cohesion via self-caging in maximally entangled rod packings
Yeonsu Jung, L. Mahadevan
Random packings of disordered rigid rods exhibit emergent cohesion, as exemplified in a nest of twigs that is self-equilibrated, free-standing structures. We analyze the geometric…
Rotational 3D printing of active-passive filaments and lattices with programmable shape morphing
Mustafa K. Abdelrahman, Jackson K. Wilt, Yeonsu Jung +6
Natural filaments, such as proteins, plant tendrils, octopus tentacles, and elephant trunks, can transform into arbitrary three-dimensional shapes that carry out vital functions. T…
Phase transitions in rolling of irregular cylinders and spheres
Daoyuan Qian, Yeonsu Jung, L. Mahadevan
When placed on an inclined plane, a perfect 2D disk or 3D sphere simply rolls down in a straight line under gravity. But how is the rolling affected if these shapes are irregular o…
Entanglement transition in random rod packings
Yeonsu Jung, Thomas Plumb-Reyes, Hao-Yu Greg Lin +1
Random packings of stiff rods are self-supporting mechanical structures stabilized by long range interactions induced by contacts. To understand the geometrical and topological com…
