Numerical modeling of static equilibria and bifurcations in bigons and bigon rings
Tian Yu, Lauren Dreier, Francesco Marmo +3
In this study, we explore the mechanics of a bigon and a bigon ring from a combination of experiments and numerical simulations. A bigon is a simple elastic network consisting of t…
Exact and approximate mechanisms for pure bending of sheets
Tian Yu, J. A. Hanna
Direct measurement of the moment-curvature response of sheets or wires up to high curvatures can aid in modeling creasing, pleating, and other forming operations. We consider theor…
Capillary imbibition in a square tube
Tian Yu, Jiajia Zhou, Masao Doi
When a square tube is brought in contact with bulk liquid, the liquid wets the corners of the tube, and creates finger-like wetted region. The wetting of the liquid then takes plac…
Overcurvature induced multistability of linked conical frusta: How a `bendy straw' holds its shape
Nakul P. Bende, Tian Yu, Nicholas A. Corbin +4
We study the origins of multiple mechanically stable states exhibited by an elastic shell comprising multiple conical frusta, a geometry common to reconfigurable corrugated structu…
