摘要: The effective jet length between the virtual origin (VO) point and target surface is very important for calculation of a shaped charge penetration. A numerical approach to determine exact position VO small caliber presented in this paper. includes formation algorithm using explicit Autodyn solver estimates precise location hydrocode analysis. This particularly when experimental flash X-ray radiograph not available. proposed model was validated by firing four charges against concrete targets. maximum difference penetration depth that calculated less than 4%.
