...C.Q. Ru The present paper studies the critical condition for negative surface tension-driven circumferential wrinkling of soft cylinders based on the linearized Steigmann–Ogden model of surface elasticity. A simple negative surface tension-mode number relation is derived explicitly for arbitrary...

... of nanomaterials and nanostructures, despite the fact that the G-M model with non-vanishing surface tension is often misused and misunderstood in the literature (see the review of the G-M model in Ref. [ 4 ]). In response, Ru [ 5 ] clarified the original version and several variants of the G-M model from...

... surface tension, an explicit expression for the change of surface energy outside the contact zone is proposed for a soft elastic substrate indented by a rigid sphere in terms of two JKR-type variables (δ , a) , where a is the radius of the contact zone and δ is the indentation depth of the rigid sphere...

... tension. Systematic parametric studies are performed to investigate the effects of both surface elasticity and surface tension on the distribution of hoop stresses on the boundary of the hole and on a line that connects the point of the applied force and the center of the hole. 23 04 2010 17 08...

Solids, 56, pp. 2298–2327 ), the surface effect induced from the surface tension and the surface Lamé constants is taken into account, and an analytical solution...

...Tong Hui; Yi-Heng Chen In this paper, the two state M -integral is extended from macrofacture to nanodefect mechanics. The question as to why the M -integral for a nanovoid or a soft nano-inclusion might be negative is clarified. It is concluded that the surface tension plays a dominant role...

...N. P. Kruyt The shear modulus of two-dimensional liquid foams in the dry limit of low liquid content has been studied theoretically. The focus is on the effect of geometrical disorder on the shear modulus (besides the influence of surface tension). Various theoretical predictions are formulated...

... surface tension surfactants capillarity Figure 3b demonstrates the concentration distribution at a distance from the bubble (line A-A) and along its diameter (line B-B). Concentration C of the undisturbed field monotonically increases with the height (curve 1), whereas the concentration...

...Simon M. Iveson; Neil W. Page The effect of liquid viscosity, surface tension and strain rate on the deformation behavior of partially saturated granular material was studied over a ten order of magnitude range of capillary number (the ratio of viscous to capillary forces). Glass spheres of average...

... is computationally demonstrated. For the unconstrained exit cases, the results make possible a separately reported study of the effects of shear, gravity, and surface tension on noise sensitive stable solutions. For unsteady cases under the assumption of constant vapor densities ρ 2 x , y , t...

...H. Haj-Hariri, Professor,; D. Poulikakos, Professor, Fellow ASME, Stability of an inviscid axisymmetric jet of uniform surface tension and flexural rigidity is investigated. It is shown that for large enough values of flexural rigidity the capillary instabilities are suppressed. The result...

...-consuming and expensive numerical methods have been used in the past. Numerical results show that neglecting the surface tension results in the underestimation of the magnitude of the liquid surface oscillation. The reason for this is explained by the influences of the Bond number and the liquid filling...
