3D Numerical Simulations of Penetration of Oil-Well Perforator into Concrete Targets

The oil-well perforator and its interaction with concrete targets are simulated with fluid-structure coupling algorithm and the new mesh motion option of the multi-material ALE formulation of LS-DYNA[1] in Version 960. Comparison of the simulation results to the experimental test data has been conducted. The simulation results show good correlation with data in tests and indicate that LS-DYNA can be used as an engineering tool to help in the prediction of perforation depth.
