Numerical Simulation of Anti-penetration Performance for Hexagonal Steel-tube-confined Concrete Target
摘要
Abstract
Hexagonal-steel-tube-confined concrete( HSTCC) target has good anti-penetration performance, and it is convenient for engineering application. The influences of edge length and thickness of hexagonal steel tube on anti-penetration performance of HSTCC targets were analyzed by ANSYS/LS-DYNA based on the penetration test of 12. 7 mm armor-piercing projectile. In view of cost-efficiency ratio,the economic performance of HSTCC target was analyzed. The results show that it can improve anti-penetration performance of HSTCC targets to enlarge the thickness and reduce edge length of steel tube. And it can get good anti-penetration and economic performance of HSTCC targets to optimize the matching of thickness and edge length of tube. The good matching is edge length with 47. 5 mm and thickness with 3. 5 mm for the projectile. The results offer reference for designing protective structure of steel-tube-confined concrete.关键词
