The damage of unconfined granite edge due to the impact of varying stiffness projectiles

A rectangular box shaped granite specimen was subjected to varying stiffness projectile impacts on its unconfined edge to investigate the rock damage. Three kinds of projectiles were used, namely chrome steel, copper 102 and pure lead. In comparison to high constraint impact, unconfined edge impac...
