The connection method of lengthening the steel tube hollow concrete-filled sandwich circular tubes and threaded connections is proposed. length, depth position are basic parameters. Twelve concrete pipes with were designed subjected to axial compression tests. compressive loading–longitudinal displacement curves, loading strain curves failure mode specimens analyzed, effects different parameter...

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...

A hydrostatic transmission is a promising technology in renewable energy harvesting, such as wind energy and wave energy, where the hydrostatic-driven electric generator is a key energy conversion component. By using analytical and experimental methods, this paper investigates the performance of a novel hydrostatic-driven electric generator which integrates the functions of an axial piston hydr...

The magnetic field produced by a rotor with alternating magnetic poles in a magnetic fluid hydrostatic bearing is numerically evaluated. There has been used a 3D program based on the finite element method (3D-FEM).

this paper investigates axial compression process of multi-layered tubes with circular cross-section under the axial loading in the quasi-static condition using experimental method. some specimens are prepared in seven different groups, namely; empty carbon/epoxy composite tubes, solid carbon/epoxy composite rods, empty copper tubes, composite tubes with silicon sealant filler, concentrically s...

Introduction: Cassini radio science data indicates that Titan is nearly in hydrostatic equilibrium [1]. We have used thermal models [2] and hydrostatic equilibrium theory [3] to derive interior models of Titan. We show as the measurement of the principal quadrupole gravitational coefficient C22 from the Radio Doppler data from Cassini spacecraft will improve our knowledge of the interior struct...
