A review on the numerical studies about KE(kinetic energy) penetrator into concrete target with mass loss is presented. There are two main ways to study the mass loss in numerical simulation: finite-element method and abrasion iterative algorithm. For each method, detailed introduction is given at home and abroad. A summary of their research, including their advantages and disadvantages, is described. Finally, some research proposals are given for further study.

The multi-step forward finite element method is presented for the numerical simulation of multi-step sheet metal forming. The traditional constitutive relationship is modified according to the multi-step forming processes, and double spreading plane based mapping method is used to obtain the initial solutions of the intermediate configurations. To verify the multi-step forward FEM, the two-step simulation of a stepped box deep-drawing part is carried out as it is in the experiment. The comparison with the results of the incremental FEM and test shows that the multi-step forward FEM is efficient for the numerical simulation of multi-step sheet metal forming processes.
