Damage quantification of intact rocks using acoustic emission energies recorded during uniaxial compression test and discrete element modeling

In this paper, acoustic emission (AE) energies recorded during 73 uniaxial compression tests on weak to very strong rock specimens have been analyzed by looking at the variations in b-values, total recorded acoustic energy and the maximum recorded energy for each test. Using 3D Particle Flow Code (PFC3D), uniaxial compression tests have been conducted on discrete element models of rocks with various strength and stiffness properties. An...
