Investigation of the Effect of Convergent Detonation on Metal Acceleration and Gurney.
MetadataShow full item record
There are longstanding interests in the analysis of explosive effects and applications in order to derive properties and predict an explosive’s behavior. This work makes a contribution to the research field of metal acceleration by the means of detonations. The effects of both planar and convergent detonation fronts on metal acceleration are investigated with respect to the Gurney model. The derived characteristic velocity, the so-called Gurney constant, is material specific and characterizes the ability of metal acceleration for a certain explosive. The hydrocode program ANSYS AUTODYN is used to calculate and analyze the simulations of this work. The focus is set on cylinder expansion tests with respect to parametric variations. In addition, cylindrical coaxial charges are explored in order to compare the different methods of realizing a convergent detonation front. Experimental and simulated results are compared, discussed and evaluated.
