Abstract

The study of deformation and broken mechanism of a solid medium loaded explosively has been paid attention to. It is more and more urgent that the mechanism of blasting and fracture be deeply studied in numerical quantities by new effective experimental methods and techniques. For this reason, the authors have made every effort to establish a new optical dynamic measuring system - superdynamic moire method measuring system (SDMM), which consists of the transmissive moire measuring system based on the multiple spark high speed camera and the reflective moire reasuring system based on the ultra high speed rotationay framing camera (GSJ type). A lot of experimental results proved that the system has good effectiveness and stable characters. First fruits have been reaped by using the SDT to study explosive mechanics and fracture mechanics.
