Abstract The jet formation and penetration behaviors of shaped charge with a reactive material double-layered liner (RM-DLL) are presented in this paper based on the AUTODYN-2D code. Numerical results show that wall thickness ratio RM-liner to metal has significant influence characteristics composite jet. As increases, tip velocity jet, pressure RM-liner, temperature RM-elements decrease. effec...

Introduction: AUTODYN [1] is used to consider the effect of altering the yield stress of geological materials on the resultant crater dimensions. This investigation is part of a series of fundamental inquiries into the sensitivities of AUTODYN, in order to fully validate the code as an appropriate tool to study large planetary impact crater formation. The majority of current AUTODYN application...

A steel plate material Hardox can be used also as a core design material for the production of ballistic barriers or traps at the shooting ranges for small arms. The article deals with the results of experiments with shooting weapon systems of a high ballistic performance and with Finite Element Method simulation of the projectile penetration upon the steel plate using the software Ansys Autody...

The shaped charge tandem warhead is an effective weapon against the ERA (explosive reactive armor). Whether the pre-warhead can reliably initiate the ERA directly determines the entire performance of the tandem warhead. The existing shaped charge pre-warhead mostly adopts a metal shaped jet, which effectively initiates the ERA, but interferes the main shaped jet. This article, on the other hand...

Introduction: Meteor Crater, Arizona, is a young (50,000yr old), relatively pristine, simple crater, and is one of the most famous and most studied on the planet. Its diameter is 1.2km with a somewhat eroded rim that originally stood at 67m, but now lies at 47m [1]. Its original depth below the surface was 180m [2] but this has been partially infilled by lake bed deposits. In addition, the floo...

Linear Shaped Charges (LSCs) have been assumed to function in the same manner as Conical Shaped Charges (CSCs) in the published literature that describes a metallic jet process for penetration. However, based on the facts that the LSC liner is composed of flat surfaces instead of the curved cone shaped liner of a CSC and the LSC detonation propagation is perpendicular to the penetrator projecti...
