Composite structures with high strength and controllable fragments driven by implosions are valuable in weaponry. This study explored a technical approach to preparing heterogeneous-gradient composite plates with a sphere-array interlayer using explo

Long rod has strong ability of penetrating into targets with high velocity because of the big ratio of L/D. In the process of the penetration, the resistance of target is so big that the deformation of the head of the projectile is severe. There are

High pressure is applied to concrete target by the projectile in hypervelocity penetration. Moreover, concrete material which undergoes large deformation is incompressible and can be depicted by liquid constitutive model. The present work modifies th

Based on the dynamic spherical cavity expansion (SCE) theory of the concrete materials and the analysis of the experimental data, both the model of the petaling penetration with low speed and the model of the round hole penetration with high speed ar

In this paper, a model of the friction coefficient in the high-speed penetration process has been used, which considers the micro-asperities of the projectile surface, the adiabatic shearing and the heat conduction on the nose of projectile. It also
