Abstract
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.
