Sand Penetration: A Near Nose Investigation of a Sand Penetration Event
This paper presents experimental and computational results of a long-rod penetrating dry granular sand at velocities near 100 m/s. The objective of this work is to develop a fundamental understanding of the formation and transmission of dynamic force chains, and the motion and fracture of the individual sand grains as the projectile passes. This is accomplished by launching a projectile along a view window, backed by sand, in order to directly view and photograph the projectile/sanddoi:10.1016/j.proeng.2013.05.069 fatcat:vkil3a5s3bflpfqaiontnhanri
