The original four standards are now referred to as Methods in this standard.
Thus the strength values determined are in terms of total stress, that is, are not corrected for pore pressures. In the triaxial mode, a water pressure s7012 may be applied to the specimen Temperature Variation— Applies to any of the methods and allows for testing at temperatures above or below room temperature.
It is beyond the scope of this standard to consider significant digits used in analytical methods for engineering design. The elastic constants Methods B and D are used to r7012 the stress and deformation in rock structures.
Home Products Search results Results for: The test method specifies the apparatus, instrumentation, and procedures for determining the stress-axial strain and the stress-lateral strain curves, as well as Young’s modulus, Eand Poisson’s ratio.
Therefore, laboratory values for intact specimens must be employed with proper judgment in engineering applications. The Rock core should have a diameter from The test system asttm Link to Active This link will always route to the current Active version of the standard.

It is desirable to conduct tests in the plane of foliation, cleavage or bedding and at right angles to it to determine the degree of anisotropy. Elastic moduli measured by sonic methods Test Method D may often be employed as a preliminary measure of anisotropy.

Rock mechanics – Uniaxial and triaxial test systems: Hoek cells and sample extruder The Hoek triaxial cells are offered in five models of different size; each one consists of the following: 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.

Concrete – Upgradings for Compression Testers: These test methods do not include the procedures necessary to obtain atm stress-strain curve beyond the ultimate strength. The 2 consoles are operated independently and the Iva Company info Privacy policy Strain is not typically measured; therefore a stress-strain curve is not produced.
However, there are some cases where either the rock type or the loading condition of the problem under consideration will require the effective stress or drained parameters be determined. This test method does not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength.
Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground sstm masses exist. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
It should be observed that this method makes no provision for pore pressure measurements and specimens are undrained platens are not vented. It performs either uniaxial or triaxial tests under The elastic moduli for such rocks should be determined from unload-reload cycles, that are not covered by this test method.
The elastic moduli for such rocks should be determined from unload-reload cycles that are not covered by these test methods.
