Abstract

Abstract

The hypervelocity impact simulation result is studied about 9.53 mm Al-shpere impacting 2.2 mm Al-target at 6.64 km/s to analyze the macro phenomena. It is shown that the SPH simulations with Steinberg material model and Mie-Grneisen EOS are in accordance with the experimental results. The diameter of the hole initially increases, then slow increases, and finally reaches a stable value. The maximum pressure at the interface between the sphere and the plate is two times higher than aluminium strength. The maximum resistance appears at the moment when the maximum diameter of sphere just intrudes the plate. Debris cloud evolves following self-similar law, and the particles of debris cloud move only inside the so-called evolving cone.
