Abstract

Abstract

Smoothed Particle Hydrodynamics (SPH) is a meshless Lagrangian hydrodynamic computational technique, and the form of SPH equations is simple. An obvious advantage of SPH is that it is meshless, thus large deformation calculations can be easily done with no connectivity complications. In this paper, the dynamic process of microjet from shocked aluminum with grooved surface is simulated with two-dimension SPH code. Jet mass, tip velocity and jet mass mass-velocity were obtained. Numerical results of microjet from grooves with the same depth and different angle are also presented, and compared with experimental ones. It is shown that SPH technique is an effective means for simulating microjet from metal free surface under shock loading.
