Abstract

Abstract

There is a lack in technology that is suitable for characterizing the shock-induced micro-jetting of metal sample with complex configuration. In this work, step signal electric probe is developed to characterize micro-jetting. The probe is designed by numerical simulation and the discharging mechanism (K+R_X model) of probe caused by micro-jetting is also verified by simulation. Quasi-continuous micro-jetting region can be directly observed on the probed signal and two kinds of dynamic processes exist: density increasing and pulling-extending to discrete state. The mass in quasi-continuous micro-jetting region is described by micro-jetting model, the equivalent size of micro-jetting is calculated based on the equivalent resistance that is obtained from the voltage signal. Thus the density of the quasi-continuous micro-jetting is obtained.
