Numerical Simulation of Shaped Charge Jet Perforating Rock by SPH-FEM Coupling Method

摘要：

The perforating process of shaped charge jet into rock target was simulated with three dimensional commercial code LS-DYNA by SPH-FEM coupling method. The penetrating pattern was reproduced and the perforating process was discussed. The computational results are in good agreement with the actual physical principle. It shows that this method can deal well with the multi-material and large deformation problems, such as shaped jet perforating rock.
