Witryna10 lis 2024 · Purpose In triaxial test, a rubber membrane encloses the specimen. The membrane is specifically thin to a thickness of no influence on the test results. However, testing coarse-grained materials in triaxial test might be challenging due to the occurrence of membrane punching. In trial tests, the angular aggregate easily … WitrynaA 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. In a triaxial shear test, stress is applied to a sample of the material being tested in a way which results in stresses …
