The Experimental Study on Velocity of Crack Spreading under Explosion Load

Wu Li; Zhang Shizhong(China University of Geosciences, Wuhan, 430074 )  
0n the basis of theoretical analysis on crack spreading velocity in brittle materials,the experiments for measuring velocities of crack spreading in marble, cement mortarand organic gIass under exp1osion load are described in this paper. The results show thatthe relationship between velocity of crack spreading under explosi0n load and time canbe we1l fitted with polyn0mial curve.
