Analysis of crystallographic texture information by the hyperspherical harmonic expansion
… concerned with measuring and analyzing the distribution of crystalline orientations in a given polycrystalline material. Traditionally, the orientation distribution function describing crystallographic orientation information is written as a linear combination of the generalized spherical …

NMR characterization of chlorhexidine in lipid-based formulations /
… is able to extract simultaneously both the orientation distribution function and the anisotropy distribution function. The spectral moments, average order parameter profiles, and longitudinal and transverse relaxation times were used to explore the structural phase behaviour of various …

Dynamics Of Orientable Particulate Suspensions: Continuum Simulations Of ‘Living’ Fluids And Meso-Scale Simulations Of Anisotropic Particle Suspensions
… microstructure of the suspension, such as orientation distribution function, particle moments to its rheological behavior, such as shear viscosity.

Incorporating Grain Size Effects in Taylor Crystal Plasticity
… or materials that contain unequal grain size distributions. These deficiencies can be overcome by incorporating both grain size and orientation characteristics into crystal plasticity theory. Homogenization relationships based on a viscoplastic Taylor-like approach are introduced along with a …

Modeling of flexible fiber motion and prediction of material properties.
… for both individual fibers and a stochastic distribution of fibers to study the variations in the transient effects between the rigid and the flexible fiber systems. Results demonstrate that the observed period decreases as the fiber flexure increases, and provide insight into the …

Fourier-Transform Infrared Studies of Polypropylene During Mechanical and Thermal Deformations
… reported for various polypropylene samples as functions of uniaxial stress, (sigma), and temperature. Generally, it was found that stress- and temperature-induced frequency shift coefficients, (alpha)(,x) and (beta)(,x), depended on the stress rate (sigma), draw ratio (lamda), molecular …

The relationship between texture and formability in sheet metals
… and expereimentally. The Crystallite Orientation Distribution. Function (CODF), expressed in terms of a series of spherical harmonics, waa used to provide a quantitative description of the textures. The crystallographic yield strength anisotropy was assessed via predicted lower bound …

Molecular simulation of liquid crystal polymer flow : a wavelet-finite element analysis
… were developed for the modeling of the molecular orientation distribution function, f, of rigid rod polymers in flow. These methods were used to investigate the liquid crystal polymer (LCP) system. Second, the distribution function calculations were incorporated into a discontinuous Galerkin …

Novel Phantoms and Post-Processing For Diffusion Spectrum Imaging
… of diffusion is inferred from the peaks in the orientation distribution function (ODF). Extensive studies using histology on macaque brain, cat cerebellum, rat hippocampus and optic tracts, and bovine tongue are qualitatively in agreement with the DSI-derived ODFs and tractography. However, …
