More Great Information on Collapsible Rubber:
Buckle in (MIT)
Motivated by the desire to determine the simplest 3-D structure that could
take advantage of mechanical instability to collapse reversibly, a group of
engineers at MIT and Harvard University were stymied — until one of them
happened across a collapsible, spherical toy that resembled the structures
they’d been exploring, but with a complex layout of 26 solid moving elements
and 48 rotating hinges.
The toy inspired the engineers to create the “buckliball,” a hollow, spherical
object made of soft rubber containing no moving parts, but fashioned with 24
carefully spaced dimples. When the air is sucked out of a buckliball with a
syringe, the thin ligaments forming columns between lateral dimples collapse.
This is the engineering equivalent of applying equal load on all beams in a
structure simultaneously to induce buckling, a phenomenon first studied by
mathematician Leonhard Euler in 1757.
When the buckliball’s thin ligaments buckle, the thicker ligaments forming
rows between dimples undergo a series of movements the researchers refer to as
a “cooperative buckling cascade.” Some of the thick ligaments rotate
clockwise, others counterclockwise — but all move simultaneously and
harmoniously, turning the original circular dimples into vertical and
horizontal ellipses in alternating patterns before ...
