Dynamic Penetration Studies in Crushed Rock under ...

A device was constructed to study dynamic penetration in crushed rock both in air and a high-vacuum (10^(-5) mm Hg) condition. The apparatus is designed to drop cylindrical, metal rods, pointed on one end, into cohesion-less crushed rock material. Dynamic penetration is studied as a function of several particle sizes and mixtures of these particle sizes.
