In this paper, a numerical analysis approach for soil digging by a chain-hammer system is presented. An explicit dynamic finite element analysis has been performed. Drucker-Prager material model is used for soil. Torque and velocity of the hammer are computed. Experiments have been conducted on the same chain-hammer system. Good agreement has been observed between experimental and FE results.
