Thus the strength values determined are in terms of total stress, that is, are not corrected for pore pressures.
Users of this standard are cautioned that compliance with Practice D does not in itself ensure reliable results. This test method does not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength. The elastic moduli for such rocks should be determined from unload-reload cycles that are not covered by these test methods.
Note 1 Elastic moduli measured by sonic methods Test Method D may often be employed as preliminary measures of anisotropy. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Therefore, laboratory values for intact specimens must be employed with proper judgment in engineering applications. Historical Version s – view previous versions of standard. Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength.
ASTM D, Test equipment Controls
The tests provide data in determining the strength of d70012, namely: It performs either uniaxial or triaxial tests under No other units of measurement are included in this standard. These test methods do not include the procedures necessary to obtain a stress-strain curve beyond the ultimate strength.
Maintenance Spares Technical trainings Warranty Academy. Hoek cells and sample extruder The Hoek triaxial cells are offered in five models of different size; each one consists of the following: Semi-automatic Uniaxial and Triaxial test system. The Rock core should have a diameter from Platens surface hardness certificate The standards prescribe a f7012 surface hardness depending on the type of test to be performed. Gshear modulus,Kbulk modulus, EYoung’s modulus, and Poisson’s ratio.
Rock mechanics – Accessories for uniaxial d70122 triaxial tests: Link to Active This link will always route to the current Active version of the standard.
Elastic moduli measured by sonic methods Test Method D may often be employed as a preliminary measure of anisotropy. Strain is not typically measured; therefore a stress-strain curve is not produced. The test d012 comprehends: Temperature Variation— Applies to any of the methods and allows for testing at temperatures above or below room temperature.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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.
ASTM D7012 – 14e1
Thus, the strength values determined are in terms of total stress and are not corrected for pore pressures. It should be observed that this method makes no provision for pore pressure measurements and specimens are undrained platens are not vented. Home Products Search results Results for:
