摘要：
A test devise for concrete penetration under action of true triaxial stress state was fabricated in our lab. The devise used a hydraulic servo control system to exert independent-controlled triaxial static loads on a cubic specimen, and high-pressure gas was employed to drive bullets and penetrate the specimen. Dynamic signals on 6 surfaces of the specimen were recorded by strain gauges on six bars. Taking M10 cement mortar as an example, penetration behaviors of cement mortar under different stress states were investigated, and the corresponding data processing method was established. Penetration differences of cubic specimens under conditions of no side limit, unidirectional one and bidirectional one were analyzed contrastively to reveal effects of stress state on penetration performance of cement mortar. It was shown that the study results provide a reference for the development in the field of protection engineering. © 2020, Editorial Office of Journal of Vibration and Shock. All right reserved.
