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.

The test is suitable for clay soils classified as soft to firm. By remoulding the sample and retesting an indication of the sensitivity of the clay can also be found. [1] The test has also been used to measure the shear strength of mortar mixes, where it has been shown to correlate with the slump value. [2]
