Application of Smoothed Particle Hydrodynamics to a Ballistic Gelatine Sample High-Speed Impact

Abstract

The study implements the smoothed particle hydrodynamics for modelling the response of the ballistic gelatine under high-speed impact. It expands the previously developed open source code SPHCOFEM by implementing the solid dynamics in combination with the Mie-Gr¨uneisen equation of state. The material properties of the ballistic gelatine are based on the literature review. Numerical simulations to verify the response of the ballistic gelatine material model reconstruct the dynamic experiment under the high-speed compression loading of a small cylindrical sample by the strain rate of 1000 s−1 and the results are compared to the published corresponding experimental data.
