2. Direct shear test - Wikipedia

   en.wikipedia.org/wiki/Direct_shear_test

   A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil [1] [2] or rock [2] material, or of discontinuities in soil or rock masses. [2] [3] The U.S. and U.K. standards defining how the test should be performed are ASTM D 3080, AASHTO T236 and BS 1377-7:1990

3. Geotechnical investigation - Wikipedia

   Direct shear test ASTM D3080. The direct shear test determines the consolidated, drained strength properties of a sample. A constant strain rate is applied to a single shear plane under a normal load, and the load response is measured. If this test is performed with different normal loads, the common shear strength parameters can be determined ...

4. Shear strength (soil) - Wikipedia

   en.wikipedia.org/wiki/Shear_strength_(soil)

   The soil is free to dilate or contract during shear if the soil is drained. In reality, soil is partially drained, somewhere between the perfectly undrained and drained idealized conditions. The shear strength of soil depends on the effective stress, the drainage conditions, the density of the particles, the rate of strain, and the direction of ...

5. Soil test - Wikipedia

   en.wikipedia.org/wiki/Soil_test

   In geotechnical engineering, a soil test can be used to determine the physical characteristics of a soil, such as its water content, void ratio or bulk density. Soil testing can also provide information related to the shear strength, rate of consolidation and permeability of the soil. The following is a non-exhaustive list of engineering soil ...

   en.wikipedia.org/wiki/Dilatancy_(granular_material)

   But as the stress approaches its peak value, the volumetric strain starts to increase. After some more shear, the soil sample has a larger volume than when the test was started. The amount of dilation depends strongly on the initial density of the soil. In general, the denser the soil, the greater the amount of volume expansion under shear.

   At Muckenhoupt’s home, Miles’ soil was used to plant a rosebush in the garden. And much of the soil resides in a planter in the backyard, next to her son’s favorite hammock chair.

8. Triaxial shear test - Wikipedia

   en.wikipedia.org/wiki/Triaxial_shear_test

   In materials science, a triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders. There are several variations on the test.

   Bourbon Street has long been party central, and little changed in the hours after Surgeon General Vivek Murthy on Friday outlined the direct link between alcohol consumption and increased cancer risk.
