Understanding and controlling hexagonal patterns of wrinkles in neo-Hookean elastic bilayer structures
Teng Zhang
A controlled surface wrinkling pattern has been widely used in diverse applications, such as stretchable electronics, smart windows, and haptics. Here, we focus on hexagonal wrinkl…
Mesoscale structure of wrinkle patterns and defect-proliferated liquid crystalline phases
Oleh Tovkach, Junbo Chen, Monica M. Ripp +3
Thin solids often develop elastic instabilities and subsequently complex, multiscale deformation patterns. Revealing the organizing principles of this spatial complexity has ramifi…
Harnessing energy landscape exploration to control the buckling of cylindrical shells
Jack Panter, Junbo Chen, Teng Zhang +1
The complexity and unpredictability of postbuckling responses in even simple thin shells have raised great challenges to emerging technologies exploiting buckling transitions. Here…
Non-uniform Curvature and Anisotropic Deformation Control Wrinkling Patterns on Tori
Xiaoxiao Zhang, Patrick T. Mather, Mark J. Bowick +1
We investigate wrinkling patterns in a tri-layer torus consisting of an expanding thin outer layer, an intermediate soft layer and an inner core with a tunable shear modulus, inspi…
Deriving a lattice model for neo-Hookean solids from finite element methods
Teng Zhang
Lattice models are popular methods for simulating deformation of solids by discretizing continuum structures into spring networks. Despite the simplicity and efficiency, most latti…
Buckling without bending: a new paradigm in morphogenesis
T. A. Engstrom, Teng Zhang, A. K. Lawton +2
A curious feature of organ and organoid morphogenesis is that in certain cases, spatial oscillations in the thickness of the growing "film" are out-of-phase with the deformation of…
Geometry underlies the mechanical stiffening and softening of an indented floating film
Monica M. Ripp, Vincent Démery, Teng Zhang +1
A basic paradigm underlying the Hookean mechanics of amorphous, isotropic solids is that small deformations are proportional to the magnitude of external forces. However, slender b…
Topological design of graphene
Bo Ni, Teng Zhang, Jiaoyan Li +2
Topological defects (e.g. pentagons, heptagons and pentagon-heptagon pairs) have been widely observed in large scale graphene and have been recognized to play important roles in ta…
A Review on Mechanics and Mechanical Properties of 2D Materials - Graphene and Beyond
Deji Akinwande, Christopher J. Brennan, J. Scott Bunch +17
Since the first successful synthesis of graphene just over a decade ago, a variety of two-dimensional (2D) materials (e.g., transition metal-dichalcogenides, hexagonal boron-nitrid…
Predicting Fracture Energies and Crack-Tip Fields of Soft Tough Materials
Teng Zhang, Shaoting Lin, Hyunwoo Yuk +1
Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materi…
