| Abstract: | The whole process of explosion formed rod-liked penetrator(EFRP) penetrating water-partitioned armor was simulated with ANSYS/LS-DYNA finite element dynamic code.The simulation results were contrasted with experimental data to validate the numerical simulation algorithm and constitutive or state equations for simulation materials,as well as to rectify the model and material parameters.The rule of EFRP penetrating water-partitioned armor,and the effects of different liner structures and detonation wave shapes to EFRP are discussed,so as to find out the correlative factors affecting the penetrating power. |
