Elastic anisotropy
WebFeb 8, 2008 · Earth's solid-iron inner core is elastically anisotropic. Sound waves propagate faster along Earth's spin axis than in the equatorial plane. This anisotropy has previously been explained by a preferred orientation of the iron alloy hexagonal crystals. However, hexagonal iron becomes increasingly isotropic on increasing temperature at pressures ... WebFeb 25, 2024 · The stability, anisotropic elastic behavior and electronic properties of trigonal In2Si2Te6, InSiTe3, In2Ge2Te6, and InGeTe3 compounds have been studied by first-principles calculations. The exchange-correlation energy of electrons has been treated using the Perdew–Burke–Ernzerhof parametrization. The calculated formation energies …

WebSep 13, 2016 · An anisotropy index seeks to quantify how directionally dependent the properties of a system are. In this article, the focus is on quantifying the elastic anisotropy of crystalline materials. Previous … WebFullscreen. Most materials are elastically anisotropic. In other words, their stiffness depends on the direction in which the stress is applied. This Demonstration illustrates the anisotropy of many cubic metals. The plot …
WebFeb 3, 2024 · Elastic anisotropy is the change of elastic characteristics with direction, and it plays an important role in the generation of cracks in the material. This calculation uses the universal anisotropy index A U, compression anisotropy percentage A camp, and shear anisotropy percentage A shear [48, 49]. The calculation formula is as follows: In the field of computer graphics, an anisotropic surface changes in appearance as it rotates about its geometric normal, as is the case with velvet. Anisotropic filtering (AF) is a method of enhancing the image quality of textures on surfaces that are far away and steeply angled with respect to the point of view. Older techniques, such as bilinear and trilinear filtering, do not take into a…
WebCompressional waves in horizontally layered media exhibit very weak long‐wave anisotropy for short offset seismic data within the physically relevant range of parameters. Shear waves have much stronger anisotropic behavior. Our results generalize the analogous results of Krey and Helbig (1956) in several respects: (1) The inequality derived by Postma (1955) … Webelastic foundation was studied by Naidu et al. [7] and by Jayachandran and Vaidyanathan [8], using the finite element method. Recently, Shen [9, 10] analysed the post-buckling of perfect and imperfect, isotropic and anisotropic thin plates under in-plane compression and resting on two-parameter elastic foundations, from which results
