Concepts which may be used in interpreting the complex rheology of liquid crystalline polymers are reviewed. Some of them are taken from the nematodynamics of low molecular weight liquid crystals as described by the Leslie—Ericksen theory, others are intrinsic to the viscoelasticity of ordinary polymers. Tentatively, these concepts are used to construct an explanation of the band texture which ...

In this article, we describe the mathematical formulation and numerical implementation of an effective parametrization viscous anisotropy orthorhombic materials produced by crystallographic preferred orientations (CPO or texture), which can be integrated into 3D geodynamic science codes. Here, approach is applied to characterize texture-induced olivine polycrystals, main constituent Earth's upp...

Improving the magnetic properties of non-oriented electrical steel (NOES) through optimization crystallographic texture has been an on-going research activity for decades. However, using traditional rolling and annealing procedures, obtained final textures were usually very similar, i.e., exhibiting {111} (γ) <110> (α) fibres, which not desired {001} (θ-fibre) optimal quality. In current work, ...

Wave propagation is used as an advanced tool of determining elastic properties of rocks. In spite of being cheap and non destructive tests of rock mechanics, due to its modernity method is not yet replacing the traditional dear and destructive tests. In order to pave ways of replacing this test and making best use of it all effective factors of such method are to be assessed. One fundamental fa...

Timelapse microscopy imaging allows for long term monitoring of biological processes however a major bottleneck in assesing experimental outcome is the need for an automated analysis framework to extract essential statistics. In this study, we use Gabor texture descriptors to generate a high dimensional feature space which is analysed with PCA to provide unsupervised characterisation of texture...

This study aimed to pave the way for industrialization of deer-based meat products. Hamburger steak prepared using deer as an alternative pork a raw material was evaluated yield after heat treatment, water-holding capacity, shear force, color, and texture. The pH all test groups found be within range 5.7-5.8, with no significant differences based on meat. venison hamburger treatment significant...

In this study, the cold rolling microstructure and static recrystallization mechanism of high strength titanium alloy Ti-3.5Al-5Mo-6V-3Cr-2Sn-0.5Fe were systematically investigated. Results show that is mainly composed elongated deformed ? grains containing micro-shear bands. After annealing at 815 °C for 2 min, fine SRXed are observed, concentrated in band, grain boundary interior grain. The s...

We describe experiments that probe the response to a point force of 2D granular systems under a variety of conditions. Using photoelastic particles to determine forces at the grain scale, we obtain ensembles of responses for the following particle types, packing geometries and conditions: monodisperse ordered hexagonal packings of disks, bidisperse packings of disks with different amount of dis...

A ductile damage model, which fully couples classical void growth at high stress triaxiality and Coulomb model the slip system scale low triaxiality, was applied for sheet specimens in an anisotropic aluminum alloy under non-proportional load path changes. The combines resolved normal shear stresses each plane directions. Reduced Texture Methodology (RTM) used to provide computational efficienc...
