    Abstract
  • The 3D elastic-plastic hydrodynamic Lagrangian-Remapping two-step Euler method was used for the micro ejection simulation of aluminum.The micro ejection calculation models have grooves on the aluminum interface with the same depth and different angles, and the numerical results of the micro-jet mass and maximum velocity thus accorded with Asay's experiment results.And then, the micro ejection calculation models with the same groove depth but much larger angle range were calculated.By the analysis of the numerical results, it is showed that the maximum velocity of the micro-jet decreases linearly with the increase of the groove angle, and the curving contour of the ejected factor versus groove angle is given.Because of the influence of metal strength and groove angle on the wave relations, the micro-jet coefficient curve is obviously nonlinear with the groove angle.
