Dynamic triaxial test
WebTriaxial tests are widely used in geotechnical engineering both in soil and rock mechanics. Specimens are axially loaded to failure while a confining pressure is constantly applied. As a result, the behavior of geomaterials is investigated in a three-dimensional stress state. The principal stresses (the maximum and minimum normal stresses ...
