Study on Numerical Simulation of Rock Blasting Based on SPH

摘要：

　　The Lagrange,Euler and ALE are often used in simulation of explosion,but each has both advantages and disadvantages in simulation of propagation of explosion shock wave,deformation and velocity of medium.And all of them could not simulate the progress of crack propagation,so this paper proposes a new method—SPH.SPH could simulate the whole rock explosion from explosion、 rock crack formation and propagation to rock fragment.
