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

   en.wikipedia.org/wiki/Geotechnical_investigation

   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. Dilatancy (granular material) - Wikipedia

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

   Dilatancy of a sample of dense sand in simple shear. The phenomenon of dilatancy can be observed in a drained simple shear test on a sample of dense sand. In the initial stage of deformation, the volumetric strain decreases as the shear strain increases. But as the stress approaches its peak value, the volumetric strain starts to increase.

5. 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 ...

7. Shear vane test - Wikipedia

   en.wikipedia.org/wiki/Shear_vane_test

   The shear vane test is a method of measuring the undrained shear strength of a cohesive soil. The test is carried out with equipment consisting of a rod with vanes mounted to it that is inserted into the ground and rotated. A gauge on the top of the rod measures the torque required to cause failure of the soil and provides a conversion to shear ...

8. Soil liquefaction - Wikipedia

   en.wikipedia.org/wiki/Soil_liquefaction

   A typical reference strain for the approximate occurrence of zero effective stress is 5% double amplitude shear strain. This is a soil test-based definition, usually performed via cyclic triaxial, cyclic direct simple shear, or cyclic torsional shear type apparatus. These tests are performed to determine a soil's resistance to liquefaction by ...

9. 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.
