Abstract
In this paper, a two-dimensional (2-D) Langrangian technique for flow field measurement under high dynamic pressure is presented, which included a set of experimental device and 2-D Lagrange composite manganin-constantan ring gages. With this kind of gage, the histories of pressure and radial displacement can be measured simultaneously at different Lagrange positions in an axisymmetric shock loading flow field. The technique has some advantages over the 1-D one, such as, simplified loading device, continuously adjustable output pressure, no restriction on sample length and the availability for the study of lateral rarefaction in shock propogation. As a preliminary application, the processes of 2-D shock initiation and attenuation in compacted TNT are measured.
