Test Method Title
Standard Test Method for Elastic Moduli of Intact Rock Core Specimens in Uniaxial Compression **ASTM has discontinued this method, the industry-accepted standard test method is now ASTM D7012D
Reference Number
ASTM D3148
Material
Rock
Test Property
Young's Modulus, Poisson's ratio
Description of Test
A rock core sample is cut to length, and the ends are machined flat. The specimen is placed in a loading frame and, if required, heated to the desired test temperature. Axial load is continuously increased on the specimen, and deformation is monitored as a function of load. The elastic constants are used to calculate the stress and deformation in rock structures.
Number of Test Specimens
Enough samples to represent a valid average of the type of rock under consideration
Test Specimen Size
Right circular cylinder, with diameter of at least 1 7/8 in and a length to diameter ratio of 2 to 2.5:1
