Extensional deformation of non-Newtonian liquid bridges

A numerical method for simulating the extensional dynamics of elongating ®laments of non-Newtonian ̄uids in a ®lament stretching rheometer is presented. The boundary element method, in conjunction with either the Oldroyd-B or the generalized multimode Upper-Convected Maxwell constitutive model, is used to calculate the transient evolution of the liquid interface, the applied force on the station...

Nanoscale deformation of a liquid surface.

We study the interaction between a solid particle and a liquid interface. A semianalytical solution of the nonlinear equation that describes the interface deformation points out the existence of a bifurcation behavior for the apex deformation as a function of the distance. We show that the apex curvature obeys a simple power-law dependency on the deformation. Relationships between physical para...

Hydraulic Failure and soil-structure deformation due to wave and draw down loading

In engineering practice submerged soils are commonly considered to be saturated and consequently the pore fluid may be regarded as incompressible. At shallow water depths this two-phase model is not in accordance with natural conditions. Even small quantities of gas bubbles change the stiffness properties of the pore fluid dramatically. In response to external fluctuating pressures, the gas bub...

Use of extension-deformation-based crystallisation of silk fibres to differentiate their functions in nature.

β-Sheet crystals play an important role in determining the stiffness, strength, and optical properties of silk and in the exhibition of silk-type-specific functions. It is important to elucidate the structural changes that occur during the stretching of silk fibres to understand the functions of different types of fibres. Herein, we elucidate the initial crystallisation behaviour of silk molecu...

Mechanical properties of silk: interplay of deformation on macroscopic and molecular length scales.

Using an in situ combination of tensile tests and x-ray diffraction, we have determined the mechanical properties of both the crystalline and the disordered phase of the biological nanocomposite silk by adapting a model from linear viscoelastic theory to the semicrystalline morphology of silk. We observe a strong interplay between morphology and mechanical properties. Silk's high extensibility ...
