Estimation of Charge Mass for High Speed Forming of Circular Plates Using Energy Method

Abstract

In this paper the explosive mass for forming a circular plate to a cone is determined using the energy method. To achieve this goal, the strain energy which is necessary to form a circular plate to a cone is calculated at first. Later the transmitted energy due to the detonation of an explosive material which is placed in a constant stand-off distance to a circular plate is specified. Equaling the strain energy and the transmitted energy, the explosive mass is figured out. Comparing the obtained results with the experiments shows the relatively acceptable compatibility.
