Shelby Tube Sampler. Utilized in the 'Standard Practice for Thin-Walled Tube Sampling of Soils for Geotechnical Purposes' (ASTM D 1587 [5]). This sampler consists of a thin-walled tube with a cutting edge at the toe. A sampler head attaches the tube to the drill rod, and contains a check valve and pressure vents.
The test uses a thick-walled sampling tube, with an outside diameter of 5.01 cm (2 in) and an inside diameter of 3.5 cm (1.375 in), and a length of at least 60 cm (24 in). The sampling tube is driven into the ground at the bottom of a borehole by blows from a hammer with a mass of 63.5 kg (140 lb) falling a distance of 75 cm (30 in). The sample ...
A thin walled beam is a type of beam (structure) that does not have a solid cross sectional area. The cross section of thin walled beams is made up from thin panels connected together. Typical closed sections include round, square, and rectangular tubes. Open sections include I-beams, T-beams, L-beams, and so on.

An equivalent definition for shear flow is the shear force V per unit length of the perimeter around a thin-walled section. Shear flow has the dimensions of force per unit of length. [ 1 ] This corresponds to units of newtons per meter in the SI system and pound-force per foot in the US.
