Under an explosive load a jet, composed by the local melted metal, would be generated and ejected from the crack of a metal plate, whose velocity may reach several kilometers per second while whose mass can only reach several milligrams per centimeter in magnitude. In the present work, high-speed photography and pulse soft X-ray radiography were used to diagnose the jet in the crack for its dynamic behavior and qualitative and quantitative measurement. A series of experiments were conducted considering different factors which include the plate material, the pressure and mode of the explosive load, the width of the crack, and the data of the jet properties and the jet mass were obtained. Based on the analysis of the experiment data, an empirical model was proposed which characterizes the jet mass varying with those different factors.
