Critical scaling and heterogeneous superdiffusion across the jamming/rigidity transition of a granular glass
TL;DR: In this paper, the dynamical properties of a dense horizontally vibrated bidisperse granular monolayer are experimentally investigated, and they provide decisive experimental evidence that this transition is a critical phenomenon, with increasingly collective and heterogeneous rearrangements occurring at length scales much smaller than the grain diameter, presumably reflecting the contact force network fluctuations.

Mechanical response of a creased sheet.
TL;DR: It is shown that a characteristic length scale, defined by the ratio of bending to hinge energies, governs whether the structure's response consists in angle opening or panel bending when a small load is applied.

Geometry and elasticity of a knitted fabric
TL;DR: In this article, a model tricot made of a single elastic thread knitted into the common pattern called stockinette was studied and a first-principle mechanical model for the displacement field was derived based on the yarn bending energy, the conservation of its total length and the topological constraints on the constitutive stitches.

Generic Bistability in Creased Conical Surfaces.
TL;DR: This work introduces a scale-free, analytical description of a very general class of snap-through, bistable patterns of creases naturally occurring at the vertices of real origami that can be used as building blocks to program and actuate the overall shape of the decorated sheet.

Local mechanical description of an elastic fold
TL;DR: An elastic model of the fold is built upon a continuous description of both the faces and the crease as a thin sheet with a non-flat reference configuration that yields the local fold properties and explains the significant differences between tensile and compression regimes.
