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…
The nonlinear buckling behavior of a complete spherical shell under uniform external pressure and homogenous natural curvature
Douglas P. Holmes, Jeong-Ho Lee, Harold S. Park +1
In this work, we consider the stability of a spherical shell under combined loading from a uniform external pressure and a homogenous natural curvature. Non-mechanical stimuli, suc…
Elasticity and Stability of Shape Changing Structures
Douglas P. Holmes
As we enter the age of designer matter - where objects can morph and change shape on command - what tools do we need to create shape-shifting structures? At the heart of an elastic…
Multistable Kirigami for Tunable Architected Materials
Yi Yang, Marcelo A. Dias, Douglas P. Holmes
In nature, materials such as ferroelastics and multiferroics can switch their microstructure in response to external stimuli, and this reconfiguration causes a simultaneous modulat…
Static bistability of spherical caps
Matteo Taffetani, Xin Jiang, Douglas P. Holmes +1
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 natu…
Snapping of Bistable, Prestressed Cylindrical Shells
Xin Jiang, Matteo Pezzulla, Huiqi Shao +2
Bistable shells can reversibly change between two stable configurations with very little energetic input. Understanding what governs the shape and snap-through criteria of these st…
