The compressive behavior of tapered piles, particularly those with circular cross-sections, has been investigated during the last few decades. However, tensile such piles rarely studied in literature. In this paper, 12 static axial tests, comprising six and were performed on instrumented uniform cross-sections using a geotechnical centrifuge. Three had correspondingly circular, square, X-shaped...

We investigate granular column collapses with different cross-sections and associate the cross-section shape influence a finite-size analysis. Previous research, confined to initially circular configurations, reviewed importance of collapse studies concluded that run-out distance scales initial aspect ratio. In this work, columns three types (square, equilateral triangular, rectangular cross-se...

Phonation models commonly rely on the assumption of a two-dimensional glottal geometry to assess kinetic and viscous flow losses. In this paper, the glottal cross-section shape is taken into account in the flow model in order to capture its influence on vocal folds oscillation. For the assessed cross-section shapes (rectangular, elliptical, or circular segment) the minimum pressure threshold en...

Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

Energy absorption capability of thin-walled structures with various cross sections has been considered by researchers up to now. These structures as energy absorbers are used widely in different industries such as automotive and aerospace and protect passengers and goods against impact. In this paper, mechanical behavior of thin-walled aluminum tubes with and without polyurethane foam filler su...

2D photonic crystal which comprises a periodic array of parallel lated dielectric constants and in [16, 20] for a periodic array rods of air of a square cross section embedded in a background of parallel dielectric rods of circular cross section whose lossless medium of higher dielectric constant. The numerical analyintersections with perpendicular planes form a triangular sis of dependence of ...

In this paper, the problem of large pure bending deformations of membrane is considered. The membrane is a sector of torus with a closed cross-section. This membrane is called a curved tube for short. We consider the homogenous, incompressible, isotropic and hyperelastic material. The external load is a constant pressure and bending couples acting at the edges. The equilibrium equations reduce ...

Two antenna capacitance problems a re solved in this paper. The motivating problem was to determine the capacitance of a biconical antenna of circular cross section immersed in a magneto-ionic medium. This is solved by reducing it to the secondary problem of determining the capacitance of a biconical antenna of elliptic cross section in an isotropic medium. The latter is solved using the sphero...

Sound transmission through ducts of constant cross section with a uniform inviscid mean flow and a constant acoustic lining (impedance wall) is classically described by a modal expansion, where the modes are eigenfunctions of the corresponding Laplace eigenvalue problem along a duct cross section. A natural extension for ducts with cross section and wall impedance that are varying slowly (compa...
