    Abstract
  • Numerical simulation of large deformation using SPH meshless method has recently become a research hotspot. In this work, we used SPH of LS-DYNA to simulate particles impact in explosive-driven compaction process. Micro-jet flow and void collapse phenomena were mapped, supporting the theory of explosive-driven compaction. Additionally, Grneisen equation of state used in LS-DYNA code was obtained by the three-term equation of state and Rankine-Hugoniot relation.
