Unconfined Compressive Strength Test of Rock
This test method specifies the apparatus, instrumentation, and procedures for determining unconfined compressive strength of intact rock core specimens. This procedure is identical to ASTM D 2938 except that the cores are tested after cutting without grinding, and neoprene caps are used on the specimen ends. Unconfined Compressive Strength Test Procedure Check the ability of the spherical seat ...

Lecture 9 Introduction to Rock Strength David Hart
The peak stress is the strength of the rock. It may fail catastrophically if the load frame is soft. Example below is for a stiff frame. The compressive strength of rock is a function of the confining pressure. As the confining pressure increases so does the strength. Goodman, Intro to Rock Mechanics

Cutting and Grinding
Grinding This step is just for UCS samples The smoother is the sample surface after cutting, the easier and faster it is to grind it. Be careful while handling the soft samples as they might chip or break during the operation. Procedure for Grinding the Samples 14 Place the sample in the V-Block and tighten the sample securely
Study of Mechanical Property of Rock under Uniaxial Cyclic
Through studying the mechanics, energy, and deformation features of rock under uniaxial cyclic loading and unloading, the findings are as follows 1 under cyclic loading and unloading, the curve of stress and strain for loading and unloading in every cycle was not superposition reciprocally but formed an acutifoliate hysteresis loop. The distribution of the hysteresis loop became denser with ...
