We study the deformation of a fluctuating crystalline sheet confined between two flat rigid walls as a simple model for layered solids where bonds among atoms {\it within} the same layer are much stronger than those {\it between} layers. When subjected to sufficiently high loads in an appropriate geometry, these solids deform and fail in unconventional ways. Recent experiments suggest that configurations named {\it ripplocations}, where a layer folds backwards over itself, are involved. These…

Displacement correlations in disordered athermal networks
We derive exact results for correlations in the displacement fields {δ~r} ≡ {δrμ=x,y} in near-crystalline athermal systems in two dimensions. We analyze the displacement correlations produced by


Universal collapse of stress and wrinkle-to-scar transition in spherically confined crystalline sheets
The construction of a unified theoretical framework that bridges inelastic crystalline defects and elastic deformations opens unique research directions that may be valuable for a broad range of material applications, such as manipulations of graphene’s electronic structure.
Deformation of layered solids: Ripplocations not basal dislocations
Abstract It has long been assumed that basal dislocations were responsible for the deformation of layered, crystalline solids. Herein we make the case that, with the notable exception of some metals
Evidence for Bulk Ripplocations in Layered Solids
Atomicistic simulations of graphite are leveraged to extend the ripplocation idea to bulk layered solids, and it is confirmed that it is essentially a buckling phenomenon.
Wrinkling hierarchy in constrained thin sheets from suspended graphene to curtains.
A formalism based on wrinklons, the localized transition zone in the merging of two wrinkles, as building blocks of the global pattern is developed and validated from hundreds of nanometers for graphene sheets to meters for ordinary curtains, which shows the universality of this description.
Elastic sheet on a liquid drop reveals wrinkling and crumpling as distinct symmetry-breaking instabilities
The data provide conclusive evidence that wrinkle patterns in highly bendable sheets are not described by classical buckling methods, but rather by a theory which assumes that wrinkles completely relax the compressive stress.
Kink bands, nonlinear elasticity and nanoindentations in graphite
Abstract Herein we report on the response of graphite single crystals––loaded parallel to their c -axis––to a 13.5 μm radius spherical diamond nanoindenter. Up to loads of 5 mN, corresponding to
Mechanics of morphological instabilities and surface wrinkling in soft materials: a review
Morphological instabilities and surface wrinkling of soft materials such as gels and biological tissues are of growing interest to a number of academic disciplines including soft lithography,

Three forms of interaction important for the case of Langmuir monolayers transferred to a substrate are discussed: Casimir-van der Waals interaction, screened charged double-layer interaction, and the Sharma potential.
Emergent structure of multidislocation ground States in curved crystals.
It is proved that an energetic hierarchy gives rise to a structural hierarchy, whereby dislocation number and scar number diverge as a/W→0 while scar length and dislocated number per scar become independent of lattice spacing.
Plastic deformation of a permanently bonded network: Stress relaxation by pleats.
We show that a flat two dimensional network of connected vertices, when stretched, may deform plastically by producing "pleats", system spanning linear structures with width comparable to the lattice
