Abstract :
Dynamic mechanical response of rock target under impact loading was analyzed by LS-DYNA finite element method.Stress-time curves in different impact velocities were obtained by sensors buried in rock target. The comparative analysis of experiment and simulation shows that the main reason of rock failure is the joint action of longitudinal compression wave and transverse sparse wave,and the conclusions can put forward reference on guiding farther dynamic mechanical experiment of rock.
