Abstract

This work investigates the effects of high-powered ultrasonics in granular material. The aim is to facilitate penetration in granular material in low mass/low gravity environments. The results show that the weight on bit requirement for penetration is significantly reduced on application of direct ultrasonic vibration, especially in high relative density substrates.
