WebA triaxial test is necessary if the complete nature of the failure of a rock is required. In this test a constant hydraulic pressure (the confining pressure) is applied to the cylindrical surface of the rock specimen, whilst applying an axial load to the ends of the sample. The axial load is increased up to the point where the specimen fails.
