Universiti Teknologi Malaysia Institutional Repository – Effects of Petrographical Rock Properties to the Strength and Behavior of Rock – Universiti Teknologi Malaysia …

The strength and behavior of rock such as compressive strength (Co), tensile strength (To), shear strength (So), friction angle (ø), young's modulus (E), poisson's ratio (υ)and rock behavior were studied by using Servo Control Hydraulic Testing Machine (SCHTM).

A Compressive Strength Criterion for Anisotropic Rock Materials

The proposed criterion, is a generalization of the Von Mises yield criterion for ductile metals, which criterion has previously been used for brittle fracture as well, both being looked upon as limits of linear elastic behaviour.

ASTM International – ASTM D4555 – 10 Standard Test Method for Determining Deformability and Strength of Weak Rock by …

The test results take into account the effect of both intact material behavior and the behavior of discontinuities contained within the specimen block. ASTM D4555 – 10 Standard Test Method for Determining Deformability and Strength of Weak Rock by an In Situ Uniaxial Compressive Test.

Scribd.com – 6.1.2 Rock Mechanics for Soil Mechanics Foundations

Rock mechanics is defined as the application of the knowledge of the mechanical behavior of rock to engineering problems dealing with rock. Rocks can be classified as being either sedimentary, igneous, or metamorphic.

University of Wollongong – An Empirical Approach in Prediction of the Roof Rock Strength in Under by S. R. Torabi, …

A comprehensive review of the literature revealed that most of the empirical equations introduced for determination of the unconfined compressive strength of rocks based on the Schmidt hammer rebound number (Rn) are not practically reliable enough as in most of the cases one formula is used for all types of rocks, alth…

Recent International Journal of Rock Mechanics and Mining Sciences Articles

Experimental results show that dynamic crack initiation toughness, dynamic tensile strength and dynamic uniaxial compressive strength can be well determined, and the HS-DIC technique provides reliable full-field strain fields in the specimens under dynamic loads.

Micromechanics of failure in porous carbonate and volcanic rocks

The phenomenological behaviors were observed to be qualitatively similar to that in a porous sedimentary rock. Synthesizing published data, we observe a systematic trend for both uniaxial compressive strength and pore collapse pressure of nonwelded tuff to decrease with increasing porosity.
