Oblique compression of square tubes with walls of different thicknesses

Thin-Walled Structures, 2023
In this paper, thin-walled aluminum square tubes with three different types of wall thickness configurations were experimentally compressed at loading angles of 0°, 10° and 15°, i.e., four walls with uniform thickness (St1t1), opposite walls with the same thickness (St1t2O and St2t1O), and opposite walls with different thicknesses (St1t2A and St2t1A ...

Partially plastic thick-walled tubes

Journal of the Franklin Institute, 1948
Abstract A theory is presented for the partial plastic yielding of thick-walled cylindrical tubes acted upon by any combination of internal pressure, external pressure and end load when the material follows an arbitrary stress-strain law. The solution combines (a) the distortion energy theory of plastic flow and (b) the effects of elastic ...

The Viscous Collapse of Thick-Walled Tubes

Journal of Applied Mechanics, 1983
The collapse of glass tubes, as used in the manufacture of optical fiber preforms, constitutes a problem involving Stokes flow, driven by surface tension and applied pressure. Undesirable, noncircular modes of deformation may grow or decay, depending on initial tube dimensions, radial viscosity variations, and the pressure differential across the tube ...

Flow-rate limitation in a uniform thin-walled collapsible tube, with comparison to a uniform thick-walled tube and a tube of tapering thickness

Journal of Fluids and Structures, 2003
Previous experiments on a tapered-thickness tube showed qualitatively different behaviour from that exhibited by a uniform thick-walled tube. To understand whether the taper or the thinner wall was responsible, similar aqueous flow-limitation experiments were conducted on a uniform thin-walled tube of the same material, with all other experimental set ...
