Discrete element simulation for investigating fragmentation mechanism of hard rock under ultrasonic vibration loading
Abstract Assisted ultrasonic vibration technique can significantly improve the efficiency of hard rock drilling in petroleum and mineral engineering. In this study, to determine the fragmentation mechanism of rocks under ultrasonic vibration, numerical simulations using the discrete element method (...
