THE UNIAXIAL COMPRESSIVE STRENGTH OF SOFT ROCK

The term soft rock is often referred to rock materials with a uniaxial compressive strength (UCS) lower than that of hard rocks and higher than that of soils. A rock material can be classified as a soft rock if it has a uniaxial compressive strength below 20 MPa, determined directly by uniaxial compression tests [1,

A Stress-Strain Model for Unconfined Concrete in

In this study, a stress-strain model for unconfined concrete with the consideration of the size effect was proposed. The compressive strength model that is based on the function of specimen width and aspect ratio was used for determining the maximum stress. In addition, in stress-strain relationship, a strain at the maximum stress was formulated as a function of compressive strength

Compressive strength of rocks PetroWiki

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders.There are several variations on the test. In a triaxial shear test, stress is applied to a sample of the material being tested in a way which results in stresses along one axis being different from the
