The constant normal load boundary condition may not be appropriate for problems where shearing is dilatancy controlled and the normal stress is not constant along the discontinuity. The test is usually conducted e5607 the undrained state with an applied constant normal load. When the normal force is not sufficient to restrain dilation, the shear mechanism consists of the overriding of the asperities.

Note 1—The term “normal force” is used in the title instead of normal stress because of the indefinable area of contact and d56607 minimal relative displacement between upper and lower halves of the specimen during testing. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design. Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors.

Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness. The actual contact areas during testing change, but the actual total contact surface is unmeasurable. However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test.

The constant normal load boundary condition is appropriate for problems where the normal stress is constant along the discontinuity.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. It is a simple asttm practical method of determining the strength and slope stability of rock, both in the field and in the laboratory.

Pervasive discontinuities joints, bedding planes, shear zones, fault zones, schistosity in a rock mass, and genesis, crystallography, texture, fabric, and other d607 can cause the rock mass to behave as an anisotropic and heterogeneous discontinuum.

Only one discontinuity per specimen can be tested. Examples of an artificial f5607 include a rock-concrete interface or a lift line from a concrete pour. ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

It is the responsibility of the user of this standard to establish appropriate safety d56007 health practices and determine the applicability of regulatory limitations prior to use. The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and asym ensure a constant vertical stress.
