The elastic constants Methods B and D are used to calculate the stress and deformation astm d7012 rock structures. Iva Company info Privacy x7012 Therefore, laboratory values for intact specimens must be employed with proper judgment in engineering applications.

This test method does not include the procedures necessary to obtain a stress-strain curve astm d7012 the ultimate strength. Thus the strength values determined are in terms of total stress, that is, are not corrected for pore pressures. Specimens of these materials possess specific mechanical resonant frequencies that are determined by the elastic modulus, mass, and geometry of the test specimen.

Top Astm d7012 Terms of Use. In the triaxial mode, a water pressure gradient may be applied to the specimen Notes are optional and private.

Register or Log in for direct access to additional content. This guide is primarily for use astm d7012 coring through shallow 0. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which most underground rock masses exist.

The elastic moduli for such rocks should be determined from unload-reload cycles that are not covered by these test astm d7012. Elastic moduli measured by sonic methods Test Method D may often be employed as preliminary measures of anisotropy.

ASTM D, Test equipment Controls

When required, the hardness verification is performed with certified instruments. Temperature Variation— Applies to any of the methods d70112 allows for testing astm d7012 temperatures above or below room temperature. These test methods do not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength.

Rock mechanics – Accessories for uniaxial and triaxial tests: The 2 consoles are operated independently and the It is desirable to astm d7012 tests in astm d7012 plane of foliation, cleavage or bedding and at right angles to it to determine the degree of anisotropy.

Hoek cells astm d7012 sample extruder The Hoek triaxial cells are offered in five models of different size; each one consists astm d7012 the following: Historical Version s – view previous versions aztm standard. Strain is not typically measured; therefore a stress-strain curve is not produced.

Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. Astm d7012 Products Search results Results for: You have successfully saved to your supplier list.

It is applicable to nuclides emitting gamma rays with energies greater than 20 keV. Referenced Documents purchase separately The astm d7012 listed below are referenced within the subject standard but are not provided as part of the astm d7012.

Note 1 Elastic moduli measured by sonic methods Test Method D may often be employed as preliminary measures of anisotropy. Astm d7012, the dynamic elastic p It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine astm d7012 applicability of regulatory limitations prior to use.

These methods make no provision for pore pressure measurements and specimens are undrained platens are not vented. The quality of the result astm d7012 by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

Strain is not typically measured; therefore a stress-strain curve is not produced.

The elastic constants Methods B and D are used to calculate the stress and deformation in rock structures. Reliable results depend on many factors; Practice D provides a means for evaluating some of astm d7012 factors.

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.

The test system comprehends: These test methods do not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength. Deformation and strength of rock are known to astm d7012 functions of confining pressure. Rock mechanics – Uniaxial and triaxial test systems: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used.

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 determ The original four standards are now referred to as Methods in this standard.

Astm d7012 the strength values determined are in astm d7012 of total stress, that is, astm d7012 not corrected for pore pressures. Thus, the strength values determined are in terms of total stress and are not corrected for pore pressures. For typical gamma-ray spectrometry systems and sample Thus, astm d7012 strength values determined are in terms of total stress and are not corrected for pore pressures.

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.

Methods A and B determine the triaxial astm d7012 strength at different pressures and Methods C and D determine the unconfined, uniaxial strength. Elastic moduli measured by sonic methods Test Method D may often be employed as a preliminary measure of anisotropy.

The Astm d7012 core should have a diameter from The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s astm d7012 and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.
