Failure Analysis and Its Numerical Simulation on Impact-damage Rock
Stress wave propagation effect and failure characteristics were studied by one-stage light-gas gun induced-plate impact experiment technology on limestone. The results show that dispersion effect and attenuation character are existed in impacting rock; failure division properties are analyzed by splitting cut observation, the results show that the failure specimen can be divided by three different failure divisions which are head failure zone, middle tension-compression failure zone and tail fracture failure zone. On this basis, impact-damaged process of rock is numerically simulated to analyze impact-damaged mechanism of limestone specimens.
