Buffering by buckling as a route for elastic deformation
D Vella - Nature Reviews Physics, 2019 - nature.com
Thin objects are deformed in a range of applications and at a range of scales, from
graphene and the actuators used in soft robots to the light sails of spacecraft. Such …

[HTML][HTML] Snap-induced morphing: From a single bistable shell to the origin of shape bifurcation in interacting shells
The bistability of embedded elements provides a natural route through which to introduce
reprogrammability to elastic meta-materials. One example of this is the soft morphable sheet …

Buckling of a pressurized hemispherical shell subjected to a probing force
J Marthelot, F López Jiménez… - Journal of …, 2017 - asmedigitalcollection.asme.org
We study the buckling of hemispherical elastic shells subjected to the combined effect of
pressure loading and a probing force. We perform an experimental investigation using thin …

Static bistability of spherical caps
Depending on its geometry, a spherical shell may exist in one of two stable states without
the application of any external force: there are two 'self-equilibrated'states, one natural and …

[HTML][HTML] Dynamics of viscoelastic snap-through
We study the dynamics of snap-through when viscoelastic effects are present. To gain
analytical insight we analyse a modified form of the Mises truss, a single-degree-of-freedom …

Frictional contact of soft polymeric shells
The classical Hertzian contact model establishes a monotonic correlation between contact
force and area. Here, we showed that the interplay between local friction and structural …

Wrapping liquids, solids, and gases in thin sheets
JD Paulsen - Annual Review of Condensed Matter Physics, 2019 - annualreviews.org
Many objects in nature and industry are wrapped in a thin sheet to enhance their chemical,
mechanical, or optical properties. Similarly, there are a variety of methods for wrapping, from …

Lifting, loading, and buckling in conical shells
Liquid crystal elastomer films that morph into cones are strikingly capable lifters. Thus
