文摘

A simple and effective one technique is used for the measurement of the spall strength. The free surface velocities of the specimen were measured by a laser detector. The spall strength of granite specimens under static pre-confining pressure is obtained. Spalling strength decreases with an increase in the static pre-confining pressure.
