Emergence of Structure in Columns of Grains and Elastic Loops
Arman Guerra, Douglas P. Holmes
It is possible to build free-standing, load-bearing structures using only rocks and loops of elastic material. We investigate how these structures emerge, and find that the necessa…
Efficient snap-through of spherical caps by applying a localized curvature stimulus
Lucia Stein-Montalvo, Jeong-Ho Lee, Yi Yang +3
In bistable actuators and other engineered devices, a homogeneous stimulus (e.g. mechanical, chemical, thermal, or magnetic) is often applied to an entire shell to initiate a snap-…
Delayed buckling of spherical shells due to viscoelastic knockdown of the critical load
Lucia Stein-Montalvo, Douglas P. Holmes, Gwennou Coupier
We performed dynamic pressure buckling experiments on defect-seeded spherical shells made of a common silicone elastomer. Unlike in quasi-static experiments, shells buckled at oste…
Packing Transitions in the Elastogranular Confinement of a Slender Loop
David J. Schunter, Regina K. Czech, Douglas P. Holmes
Confined thin structures are ubiquitous in nature. Spatial and length constraints have led to a number of novel packing strategies at both the micro-scale, as when DNA packages ins…
Elastogranularity in Binary Granular Mixtures
David J. Schunter, Matthew Boucher, Douglas P. Holmes
Frustration arises for a broad class of physical systems where confinement (geometric) or the presence of a perturbation (kinematic) prevents equilibration to a minimum energy stat…
Buckling of geometrically confined shells
Lucia Stein-Montalvo, Paul Costa, Matteo Pezzulla +1
We study the periodic buckling patterns that emerge when elastic shells are subjected to geometric confinement. Residual swelling provides access to range of shapes (saddles, rolle…
