On the incremental equations in surface elasticity (2024)
Journal Article

We derive the incremental equations for a hyperelastic solid that incorporate surface tension effect by assuming that the surface energy is a general function of the surface deformation gradient. The incremental equations take the same simple form as... Read More about On the incremental equations in surface elasticity.

New mountain ridge modes in a film/substrate bilayer (2023)
Journal Article

This article is concerned with the buckling of a film-substrate bilayer in a state of plane strain when it is subjected to a uni-axial compression along its free surface. Previous numerical simulations have indicated that pre-stretching the substrate... Read More about New mountain ridge modes in a film/substrate bilayer.

Stochastic flutter analysis of a three-degree-of-freedom airfoil under vertical turbulence disturbance (2023)
Journal Article

This paper investigates the nonlinear stochastic dynamic response of a three-degree-of-freedom(3-DOF) airfoil with high substructural nonlinearity under vertical turbulent disturbances. Considering a two-dimensional flow field, the Dryden turbulence... Read More about Stochastic flutter analysis of a three-degree-of-freedom airfoil under vertical turbulence disturbance.

Axisymmetric necking of a circular electrodes-coated dielectric membrane (2023)
Journal Article

We investigate the stability of a circular electrodes-coated dielectric membrane under the combined action of an electric field and all-round in-plane tension. It is known that such a membrane is susceptible to the limiting point instability (also kn... Read More about Axisymmetric necking of a circular electrodes-coated dielectric membrane.

A one-dimensional model for axisymmetric deformations of an inflated hyperelastic tube of finite wall thickness (2023)
Journal Article

We derive a one-dimensional (1d) model for the analysis of bulging or necking in an inflated hy?perelastic tube of finite wall thickness from the three-dimensional (3d) finite elasticity theory by applying the dimension reduction methodology propose...

Localized bulging of an inflated rubber tube with fixed ends (2022)
Journal Article

When a rubber tube with free ends is inflated under volume control, the pressure will first reach a maximum and then decrease monotonically to approach a constant asymptote. The pressure maximum corresponds to the initiation of a localized bulge and... Read More about Localized bulging of an inflated rubber tube with fixed ends.

A refined model for the buckling of film/substrate bilayers (2022)
Journal Article

The classical reduced model for film/substrate bilayers is the one in which the film is governed by the Euler–Bernoulli beam equation, and the substrate is replaced by an array of springs (the so-called Winkler foundation assumption). We derive a ref... Read More about A refined model for the buckling of film/substrate bilayers.

An analytic derivation of the bifurcation conditions for localization in hyperelastic tubes and sheets (2022)
Journal Article

We provide an analytic derivation of the bifurcation conditions for localized bulging in an inflated hyperelastic tube of arbitrary wall thickness and axisymmetric necking in a hyperelastic sheet under equibiaxial stretching. It has previously been s... Read More about An analytic derivation of the bifurcation conditions for localization in hyperelastic tubes and sheets.

Axisymmetric necking versus Treloar–Kearsley instability in a hyperelastic sheet under equibiaxial stretching (2022)
Journal Article

We consider bifurcations from the homogeneous solution of a circular or square hyperelastic sheet that is subjected to equibiaxial stretching under either force- or displacement-controlled edge conditions. We derive the condition for axisymmetric nec... Read More about Axisymmetric necking versus Treloar–Kearsley instability in a hyperelastic sheet under equibiaxial stretching.

Post-bifurcation behaviour of elasto-capillary necking and bulging in soft tubes (2021)
Journal Article

Previous linear bifurcation analyses have evidenced that an axially stretched soft cylindrical tube may develop an infinite-wavelength (localized) instability when one or both of its lateral surfaces are under sufficient surface tension. Phase transi... Read More about Post-bifurcation behaviour of elasto-capillary necking and bulging in soft tubes.

On propagation of waves in pressurized fiber-reinforced hyperelastic tubes based on a reduced model (2021)
Journal Article

A refined dynamic finite-strain shell theory for incompressible hyperelastic materials was developed by the authors recently. In this paper, we first derive the associated linearized incremental theory, and then use it to investigate wave propagation...

Post-buckling of an elastic half-space coated by double layers (2021)
Journal Article

We investigate the buckling and post-buckling properties of a hyperelastic half-space coated by two hyperelastic layers when the composite structure is subjected to a uniaxial compression. In the case of a half-space coated with a single layer, it is... Read More about Post-buckling of an elastic half-space coated by double layers.

Elasto-capillary circumferential buckling of soft tubes under axial loading: existence and competition with localised beading and periodic axial modes (2021)
Journal Article

AbstractWe provide an extension to previous analysis of the localised beading instability of soft slender tubes under surface tension and axial stretching. The primary questions pondered here are as follows: under what loading conditions, if any, can...

Localised bifurcation in soft cylindrical tubes under axial stretching and surface tension (2021)
Journal Article

We investigate localised bulging or necking in an incompressible, hyperelastic cylindrical tube under axial stretching and surface tension. Three cases are considered in which the tube is subjected to different constraints. In case 1 the inner and ou...

Necking, Beading, and Bulging in Soft Elastic Cylinders (2021)
Journal Article

Due to surface tension, a beading instability takes place in a long enough fluid column that results in the breakup of the column and the formation of smaller packets with the same overall volume but a smaller surface area. Similarly, a soft elastic... Read More about Necking, Beading, and Bulging in Soft Elastic Cylinders.
