Abstract : The objective of this investigation was to obtain preliminary information on the damage that results to a model silo closure when impacted by simulated ejecta from a blast crater. The debris impact loading condition was achieved by impacting one-third scale models of various closures considered in the Hard Rock Silo (HRS) program with a 22-1/2-inch-diameter spherical concrete projectile fired from a 2-foot-diameter horizontal shock tube. The impact velocity was approximately 300 fps. High-speed motion pictures were taken of the impact shots to verify the projectile velocity and to document the sequence of damage at impact. The test program consisted of five closures being impacted a total of eight times. (Author)
