A summary of peak shear stress, peak asrm shear stresses, and residual shear stresses A figure of peak residual stress and residual shear stress vs. Link to Active This link will always route to the current Active version of the standard. Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors.

Two versions are available:. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note r5607 term “normal force” is used in the title instead of normal stress because of the indefinable area of contact and the 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. The values given in parentheses are mathematical conversions to inch-pound units, which are provided for information only and are not considered standard. Samples should be concrete or rock cores with a diameter no greater than Therefore, it may be necessary to handle specimens in accordance with Practice D and to document moisture conditions in some manner in the data collection.

When the normal load is large enough to completely restrain dilation, the shear mechanism consists of the shearing off of the asperities.

Print and complete the following order form. ASTM D Use This test method establishes requirements and laboratory procedures for performing direct adtm strength tests on rock specimens. Note 2—Since this test method makes no provision for the measurement of pore pressures, the strength values determined are expressed in terms of total stress, uncorrected for pore pressure. Two versions can be used to complete the testing configuration: Results Produced Report of direct shear strengths five to nine pages depending on sample type including the following: In addition, axtm are representative of the significant digits that generally should be retained.

Relationships derived from the test data include shear strength d55607 normal stress and shear stress versus shear displacement shear stiffness. During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous or have planes of weakness, including natural or artificial discontinuities.

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 to ensure a constant vertical stress.

Sliding on and shearing of the asperities can occur simultaneously.

It is a simple and practical method of determining the strength and slope stability of rock, both in the field and in the laboratory. Since this test method makes no provision for the measurement of pore pressures, the strength values determined are expressed in terms of total stress, uncorrected for pore pressure.

This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement c5607 stiffness. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test.

When the normal force is not sufficient to restrain dilation, the shear mechanism consists of the overriding of the asperities.

Order Form f5607 Email complete form to contact listed below. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.

However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open c5607 could be considered a drained test. Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. The test is usually conducted in the undrained state with an applied constant normal load. Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.

Only one discontinuity per specimen can be tested.
