Nonlinear dynamics of a nematic liquid crystal in the presence of a shear flow
… behaviour of the system: the temperature and the shear rate, and by employing continuation and bifurcation theory we describe the different time dependent states for the two and three dimensional cases.<br/><br/>For the two dimensional case we compute the steady state solution branches finding …

Development of Sustainable Thermoplastic Elastomers
… compression molding. Large amplitude oscillatory shear was employed at a temperature below ODT to align the randomly oriented grains. The predominant orientation was determined to be hexagonally close-packed spherical domains with the {0001} planes parallel to the shear plane, with a small …

Transient Shear Flow Rheology of Concentrated Long Glass Fiber Suspensions in a Sliding Plate Rheometer
… viscosity growth measurements at the startup of shear flow were performed on long glass fiber-filled polypropylene. Samples were prepared with fibers pre-oriented either in 1-direction, 3-direction or random in 1-3 plane, where the 1-direction is the direction of shear motion, the 2-direction is …

Determination of Lateral Resistance of Deck Tie Fasteners in Smooth Top Bridge Girders
… was found to be a function of the area of the shear plane in a dapped tie. A preliminary equation for calculating the total lateral resistance capacity was developed utilizing superposition of all three resistance contributions. Lateral demand loads were compared with reported lateral capacity …

An Experimental Study of the Dynamic Behavior of Slickensided Surfaces
When a clay soil is sheared, clay particles along the shear plane become aligned in the direction of shear, forming "slickensided" surfaces. Slickensided surfaces are often observed along the sliding plane in field landslides. Because the clay particles along a slickensided surface are already …

Binary mixtures of rod-like colloids
In this work we investigate the shear induced instabilities occurring in colloidal binary mixtures of rigid anisotropic particles. To this end, we derive a theoretical framework including equilibrium and non-equilibrium methods. The equilibrium description is derived on the basis of microscopic …

Experimental deformation of forsterite, wadsleyite and ringwoodite: Implications for seismic anisotropy of the Earth’s mantle
… investigated. Deformation has been achieved by shear using the Kawai-type multianvil apparatus. Complementary experiments on forsterite have been performed in the newly developed Deformation-DIA. Some of them have been carried out on a synchrotron beam line to perform in-situ stress and strain …

Adsorption of dextrin onto sulphide minerals and its effect on the differential flotation of the Inco matte
… in an extended adsorption layer that drives the shear plane further away from the interface. Conductometric and ATR-FTIR tests confirm that dextrin interacts strongly with Ni3S2 most likely through chemical bonding, while its interaction with chalcocite is physical in nature. This is a brand name …

Strain path partitioning during forceful emplacement of the Papoose Flat pluton, Inyo Mountains, CA
… units reveals large components of either pure shear or simple shear deformation. C-axis fabric analysis of quartz tectonites within veins in the gneissic border of the pluton, and quartzites within the pluton aureole, indicate that quartz tectonites deformed under approximately simple shear …

Nonlinear macroscopic description of liquid crystalline elastomers in external fields
… Using our model, we first investigate the shear deformation of a nematic SCLSCE. If the shear plane contains the director, the latter will be reoriented due to the mechanical deformation. In addition, however, we find as a nonlinear effect that the director reorientation acts back onto the …

Dynamics and statistics of hydrodynamically interacting particles in laminar flows
… why the diffusion constant in the potential plane shows a pronounced local maximum around l/b equal 3/2. Furthermore, the influence of the spring rigidity and the hydrodynamic interaction on the diffusive motion are examined as well as the dumbbell statistics. If the dumbbell is driven by an …

Collective dynamics in flowing suspensions of swimming micro-organisms
… micro-organisms in the presence of an external shear flow. Doing so allows us to simulate more realistic situations where ambient flow is present, as in oceans where motility could influence bacterial ecology and the role of bacteria in oceanic biogeochemistry. Moreover, we can investigate their …

Bacteria in shear flow
… of fluid flow: creeping flow in soil, highly sheared flow in bodily conduits, and turbulent flow in rivers, streams, lakes, and oceans, as well as anthropogenic habitats such as bioreactors, heat exchangers and water supply systems. The presence of flow not only affects how bacteria are …

The role and fate of fluid inclusions in natural and experimental deformation
… grain boundary migration. Results indicate that shearing accommodated by dislocation creep rearranges and aligns FIs into bands at a low angle to the shear plane. The arrangement of FIs into low-angle bands is interpreted to have established under a pressure gradient that focuses fluids in …

In-situ electron imaging of oxidation and reduction of rutile (TiO2) nanocrystals and interaction with palladium
… of the planar defects, called crystallographic shear planes (CSPs). The CSPs transform from {101} to {211} orientations when the oxygen partial pressure is increased. Ex-situ observation of the CSP structures using scanning TEM (STEM) show that the {211} CSPs contain a high concentration of the …
