Effect of Specimen Size on Confined Compression Testing of Rock Cores

Abstract

The axial stress in the rock depends upon the ratio of the rock and piston areas and the difference in the confining pressure and the axial chamber pressure. In each of the tests to be performed in this program the rock core is loaded hydrostatically up to the predetermined confining pressure, and then the axial pressure is increased gradually to the desired value. At least one load- unload-reload cycle on each specimen was planned. During the reload the axial stress is increased until the core fails or the capacity of the cell is attained, whichever is lower.
