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 …

Recent advances in three dimensional (3D) printing technology that allow multiple materials
to be printed within each layer enable the creation of materials and components with …

For decades, nanoindentation has been used for measuring mechanical properties of films
with the widely used assumption that if the indentation depth does not exceed 10% of the …

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 …

We study the effect of a dimplelike geometric imperfection on the critical buckling load of
spherical elastic shells under pressure loading. This investigation combines precision …

Elastic gridshells comprise an initially planar network of elastic rods that are actuated into a
shell-like structure by loading their extremities. The resulting actuated form derives from the …

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 …

Curvature and mechanics are intimately connected for thin materials, and this coupling
between geometry and physical properties is readily seen in folded structures from intestinal …

Elastic spherical shells loaded under uniform pressure are subject to equal and opposite
compressive probing forces at their poles to trigger and explore buckling. When the shells …

Ring origami is a new strategy to design bistable foldable/deployable structures by
assembling multiple rings with the same geometry. The successful folding of ring origami …
