Overburden Layer With Oblique Penetration Study Concrete Structure

The earth penetrator penetration,who can offer significant guidance to ammunition design and defense design,is always the key research topic of military domain and defense domain. In the paper,based on ANSYS/LS-DYNA software,the earth penetrator oblique penetration is simulated and analyzed. Firstly,the research history and the development of earth penetrator penetration are reviewed,and the study methods and the theory basis are introduced in brief. Through the simulations that the projectile penetrated the soil target,the movement paths in medium are obtained,and the penetration effects resulting from the initial conditions and the projectile shapes are summarized. Then the process that the projectile penetrates the soil-concrete target is analyzed, and the penetration path in two-layer medium is obtained,as well as the relation between the path and the initial conditions. The study results have reference value to the design of earth penetrator warhead and fortification.
