Triaxial tests are used along with other tests to make such engineering predictions. During the shearing, a granular material will typically have a net gain or loss of volume. If it had originally been in a dense state, then it typically gains volume, a characteristic known as Reynolds' dilatancy . Zobacz więcej 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 … Zobacz więcej There are several variations of the triaxial test: Consolidated drained (CD) In a 'consolidated drained' test the sample is consolidated and sheared in compression slowly to allow pore pressures built … Zobacz więcej • Civil engineering • Direct shear test • Earthworks (engineering) • Effective stress • Geotechnical engineering Zobacz więcej For soil samples, the specimen is contained in a cylindrical latex sleeve with a flat, circular metal plate or platen closing off the top and bottom ends. This cylinder is placed into a bath of a hydraulic fluid to provide pressure along the sides of the cylinder. The … Zobacz więcej The list is not complete; only the main standards are included.
