Structure formation in anisotropic
Density linear perturbations in Einstein-Cartan two fluid cosmolo-gies where the outer model is an isotropic Friedmann solution with closed model while the inner model is a flat anisotropic Einstein-Cartan (EC) cosmology with shear are computed by taking into consideration superhorizon situations.This situation is in agreement with the present isotropy of the Cosmic Background Radiation where t...
متن کاملParametric Study of Steel-Lined Pressure Shafts in Anisotropic Rock
Steel-lined pressure tunnels and shafts are used to convey water from the reservoir to the turbines in high-head hydroelectric power plants. An axisymmetrical multilayer model is often considered by engineers for the design of the steel liner. Stresses and deformations can then be computed with a closed-form analytical solution in isotropic rock. When the rock is anisotropic, the lowest elastic...
متن کاملSteel-lined Pressure Tunnels and Shafts in Anisotropic Rock
For the design of steel-lined pressure tunnels and shafts in anisotropic rock, it is common practice to assume for the computation that the system stands in isotropic medium with the lowest stiffness measured in situ. In this paper, stresses and displacements in the steel liner of a particular steel-lined pressure tunnel are numerically assessed taking into account the anisotropic behavior of t...
متن کاملChip Formation and Minimum Chip Thickness in Micro-milling
In the current context of miniaturization, micro-machining processes are in full expansion. One of them is micro-milling. Although micro-milling is based on the same principle as macro-milling, the phenomena of micro-cutting are not a simple scaling of macrocutting. A significant difference is the chip formation involving the phenomenon of minimum chip thickness. In micro-milling the depth of c...
متن کاملDouble grating formation in anisotropic photorefractive crystals
Double gratings form in anisotropic photorefractive crystals when two plane waves intersecting inside the crystal have both extraordinary and ordinary wave components. The effect can be observed by reading out the two gratings with extraordinary or ordinary light. Experiments confirm the theoretical predictions. The relevance of these results in using photorefractive crystals for holographic st...
