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…
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…
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…
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…
