Pressurised cylindrical channels made of soft materials are ubiquitous in biological systems, soft robotics and metamaterial designs. In this paper, we study large deformation and subsequent instability of a thick-walled and compressible hyperelastic cylinder under internal pressure and external constraints. The applied pressure can lead to elastic bifurcations along the axial or circumferential direction. Perturbation theory is used to derive the partial differential equations that govern the… Expand

Peristaltic Elastic Instability in an Inflated Cylindrical Channel.
TLDR
This work combines theory and numerics to fully characterize the instability in a channel with initial radius a through an incompressible bulk neo-Hookean solid with shear modulus μ, and shows instability occurs supercritically with wavelength 12.278…a when the cavity pressure exceeds 2.052…μ.

TLDR
This study suggests that skin microrelief could be the dominant factor conditioning micro-wrinkle characteristics for moderate elastic modulus ratios between the two layers, beyond stiffness ratios of 100. Expand

Under pressure: Hydrogel swelling in a granular medium
TLDR
Visualization reveals that confinement in a granular medium hinders hydrogel swelling, with implications for agriculture and quantitative principles to predict how hydrogels behave in confinement are provided, potentially improving their use in agriculture as well as informing other applications such as oil recovery, construction, mechanobiology, and filtration.

Effects of pre-stretch, compressibility and material constitution on the period-doubling secondary bifurcation of a film/substrate bilayer
We refine a previously proposed semi-analytical method, and use it to study the effects of pre-stretch, compressibility and material constitution on the period-doubling secondary bifurcation of aExpand
