Rockfall tests conducted in Europe and Japan have developed energy equations consistent with the Hertz Contact Theory. A confirming independent approach was developed using Conservation of Momentum, to estimate forces with accidental impact on buried utilities, during Dynamic Compaction on soil...
This message is being sent to share my experience with designing a rockfall shed for a 10' 80,000# rock falling from 350'= 115 mph impact. Have considerable information to share including from Dr. Hiroshi Yoshida-Japan, Sandia Nat. Laboratories, and others on computing impact effects [ie via...
