Abstract
This study aims to practically evaluate the radial anisotropy of rock material through laboratory testing of rock discs. The anisotropy was assessed by measuring the diameter, P-wave velocity, and Brazilian elastic modulus in the radial direction at different angular distances using three representative rock types, granite, marble, and sandstone. The anisotropy of all the properties measured in each rock type was distinctly evident. The results showed that sandstone exhibited a larger diametrical anisotropy compared to the other rock types. The P-wave velocity and Brazilian Elastic Modulus (EB) were the highest in granite.
