In order to study the overload characteristics of projectile aslant penetrating through hard target in different spacing

the article had made the simulation on the process where the projectile penetrates aslant through three-tier concrete target in different spacing by using the software named ANSYS/LS-DYNA

obtaining the curves which could reflect that how the penetrated velocity and acceleration changed.The rule can be found via analyzing the curves.The findings can provide a theoretical basis for designing hard target smart fuze which detonates by means of counting layers and holes

and a referential value for the selection of acceleration sensor which can be against the high overload.
